[Population registration and censuses. The Chinese tradition].

"The case of China is in many ways exemplary, due to both its extremely long history and the fact that the Chinese approach influenced other countries over the course of the centuries, and can thus be viewed as a model. The first ¿censuses' were intended as an administrative tool, to manage lists of those subject to the corvee. As administrative regulations evolved, these lists were made obsolete and replaced, with the change of dynasty in 1644, by fiscal records. From 1740 to 1780, in order to link economic knowledge--especially grain prices--to the demographic situation, the central government urged local authorities to produce nominative records. Genealogies, rich in information, were another source of knowledge. With certain alterations, the Chinese model spread into the surrounding region, including Japan, Vietnam and Korea."

Fertility levels in Australia: what can the 1991 census tell us?

"The information which can be gathered from the 1991 [Australian] Census on trends in fertility is limited. But an analysis of the one per cent users' sample tape indicates that women with advanced educational qualifications are now having families which are considerably smaller than those of women who have no post-school qualifications."

How many Samoans? An evaluation of the 1980 census count of Samoans in the United States.

"This paper reports the results of applying demographic methods, in combination with assumptions about vital rates and migration, to estimate the total Samoan population of the United States in 1980." The authors conclude that the most plausible estimate of the Samoan population in the United States in 1980 is between 46,600 and 50,800. These estimates are 10 to 17.5 percent higher than the census count.

Alzheimer disease in the US population: prevalence estimates using the 2000 census.

CONTEXT: Current and future estimates of Alzheimer disease (AD) are essential for public health planning. OBJECTIVE: To provide prevalence estimates of AD for the US population from 2000 through 2050. DESIGN: Alzheimer disease incidence estimates from a population-based, biracial, urban study, using a stratified random sampling design, were converted to prevalence estimates and applied to US Census Bureau estimates of US population growth. SETTING: A geographically defined community of 3 adjacent neighborhoods in Chicago, Ill, applied to the US population. PARTICIPANTS: Alzheimer disease incidence was measured in 3838 persons free of AD at baseline; 835 persons were evaluated for disease incidence. Main Outcome Measure Current and future estimates of prevalence of clinically diagnosed AD in the US population. RESULTS: In 2000, there were 4.5 million persons with AD in the US population. By 2050, this number will increase by almost 3-fold, to 13.2 million. Owing to the rapid growth of the oldest age groups of the US population, the number who are 85 years and older will more than quadruple to 8.0 million. The number who are 75 to 84 years old will double to 4.8 million, while the number who are 65 to 74 years old will remain fairly constant at 0.3 to 0.5 million. CONCLUSION: The number of persons with AD in the US population will continue to increase unless new discoveries facilitate prevention of the disease.

Census of brown lemurs (Eulemur fulvus sspp.) in southeastern Madagascar: methods-testing and conservation implications.

Four forest areas were censused in southeastern Madagascar from June-August 1995 to estimate local population densities and habitat conditions for two threatened subspecies of brown lemur (Eulemur fulvus collaris and Eulemur fulvus albocollaris). Survey transects varied in length (1-3.5 km) and in surveillance frequency (three to seven times). Additional test surveys were conducted at the Parc National de Ranomafana to compare transect methods in an area with known population densities of Eulemur fulvus. Based on these tests, we demonstrate that the use of existing trails for transects can result in a close estimate of local population size, although more replications and longer transects increase precision. Results from regional surveys indicate considerably smaller population densities for E. f. albocollaris (0.086 animals/ha). In contrast, E. f. collaris densities were relatively high (.107 animals/ha) at Midongy-Sud. We also noted variation among sites in the density of lianas, which was positively correlated with local population density (a possible indication of habitat degradation). More generally, habitats in E. f. albocollaris's range suffered from fragmentation, reduction in forest area, logging, and potentially greater hunting pressure. Based on these results, it is apparent that more immediate steps are necessary to preserve E. f. albocollaris populations and habitats.

Census in a rural area of Ethiopia: methodology and results.

A census and an ecologic survey were performed in 39 villages of a rural district of Arsi Region, Ethiopia, in difficult field circumstances. Information on age, ethnic group, education and family relationship, as well as data on health facilities and availability of basic services were collected. Supervised students, working in teams, were used as interviewers. Communities were involved through plenary meetings and community health agents participated in the data collection process. A total of 64,714 people in 12,152 households were registered. The repeatability of age assessment was investigated by comparing the results from two villages with data obtained in a pilot study carried out 6 months earlier. The technical error was only 0.80 and 1.67 in the 0-5 and 6-15 age-groups, respectively. Three percent of the total population was under one year, less than previously estimated. This may, in part, be due to the family planning programme in the region. Eighteen percent of the households were headed by females. School attendance was less common among females and in the Oromo ethnic group. The availability of basic services, including safe water and basic sanitation supplies, was very poor in the area.

Population census of the white-headed langur (Trachypithecus leucocephalus) at Longrui Karst Hills, Guangxi, China.

A population census of white-headed langurs (Trachypithecus leucocephalus) was conducted using sleeping-site counts and the line-transect method from July to August 2002 at the Longrui Karst Hills, Guangxi, China. This area had been the largest habitat of the langurs across their range before the 1990s. While our survey revealed 146 old sleeping-sites, no white-headed langurs or fresh sleeping-sites were found in this area. Our study indicated that there had previously been a large population of langurs at Longrui Karst Hills, but now the langurs are possibly locally extinct in this area. If langurs still exist within the area, the population density must be very low. Interviews with local people confirmed that the number of white-headed langurs has been decreasing since the 1980s. Poaching was very common in the past and continues to be a problem at present, and it is likely that this has caused the decrease in the white-headed langur population at Longrui Karst Hills.

Mapping and measuring social disparities in premature mortality: the impact of census tract poverty within and across Boston neighborhoods, 1999-2001.

The identification and documentation of health disparities are important functions of public health surveillance. These disparities, typically falling along lines defined by gender, race/ethnicity, and social class, are often made visible in urban settings as geographic disparities in health between neighborhoods. Recognizing that premature mortality is a powerful indicator of disparities in both health status and access to health care that can readily be monitored using routinely available public health surveillance data, we undertook a systematic analysis of spatial variation in premature mortality in Boston (1999-2001) across neighborhoods and sub-neighborhoods in relation to census tract (CT) poverty. Using a multilevel model based framework, we estimated that the incidence of premature mortality was 1.39 times higher (95% credible interval 1.09-1.78) among persons living in the most economically deprived CTs (>/=20% below poverty) compared to those in the least impoverished tracts (<5% below poverty). We present maps of model-based standardized mortality ratios that show substantial within-neighborhood variation in premature mortality and a sizeable decrease in spatial variation after adjustment for CT poverty. Additionally, we present maps of model-based direct standardized rates that can more readily be compared to externally published rates and targets, as well as maps of the population attributable fraction that show that in some of Boston's poorest neighborhoods, the proportion of excess deaths associated with CT poverty reaches 25-30%. We recommend that these methods be incorporated into routine analyses of public health surveillance data to highlight continuing social disparities in premature mortality.

Pulmonary thromboembolism in Asians/Pacific Islanders in the United States: analysis of data from the National Hospital Discharge Survey and the United States Bureau of the Census.

PURPOSE: To assess the rate of diagnosis of deep venous thrombosis, pulmonary embolism, and venous thromboembolism; the incidence in hospitalized patients; and mortality from pulmonary embolism among Asians/Pacific Islanders in the United States. METHODS: The number of patients discharged from hospitals with a diagnostic code for pulmonary embolism or deep venous thrombosis from 1990 through 1999 was obtained from the National Hospital Discharge Survey. Population estimates and deaths from pulmonary embolism from 1990 through 1998 were obtained from the United States Bureau of the Census. RESULTS: Rate ratios of 10-year age-adjusted rates of diagnosis of deep venous thrombosis, pulmonary embolism, and venous thromboembolism comparing Asians/Pacific Islanders with whites and African Americans ranged from 0.16 to 0.21. Rate ratios comparing incidences in hospitalized patients ranged from 0.32 to 0.42. The age-adjusted rate ratio of mortality in "others" (which included Asians/Pacific Islanders) was 0.29 (95% confidence interval [CI]: 0.01 to 0.87) compared with whites and 0.14 (95% CI: 0.0 to 0.58) compared with African Americans. CONCLUSION: Rates of deep venous thrombosis, pulmonary embolism, and venous thromboembolism; incidences in hospitalized patients; and the mortality rate from pulmonary embolism were markedly lower in Asians/Pacific Islanders than in whites and African Americans. Clinical assessment of the prior probability of venous thromboembolic disease at the bedside should probably be adjusted based on these ethnic differences.

[Current census rates in inpatients hospitalized in the Hospital de Poniente in Almería [Spain]].

OBJECTIVE: To study the current census rate of patients admitted to an internal medicine service. METHOD: We studied all patients admitted to the internal medicine service from January 1 to August 31, 2000 whose addresses were registered in four local authorities of our hospital district. We made exhaustive searches to ascertain whether these patients were included in the register in September 2000. RESULTS: We analyzed 1,095 admissions from a total of 1,759 up to August 31, 2000. Twenty-four percent corresponded to patients who were not registered. Fifty-eight percent of those not registered were aged more than 70 years. Twenty-seven percent of patients aged less than 40 years, most of whom were immigrants, were also unregistered. CONCLUSIONS: Twenty-four percent of the admissions to the internal medicine service that were studied corresponded to patients who were not registered with their respective local authorities. A possible explanation is the large immigrant population and the lack of registration among the elderly.

Reproductive health in school-based health centers: findings from the 1998-99 census of school-based health centers.

PURPOSE: To describe the state of reproductive health services, including access to contraception and health center policies, among school-based health centers (SBHCs) serving adolescents in the United States METHODS: We examined questionnaire data on provision of reproductive health services from the 1998-99 Census of School-Based Health Centers (response rate 70%). We examined 551 SBHCs in schools with high or middle school grades. We used logistic regression to define factors independently associated with services and policies. RESULTS: Most SBHCs (76%) were open full-time; over one-half (51%) of centers had opened in the past 4 years. Services provided, either on-site or by referral, included gynecological examinations (95%), pregnancy testing (96%), sexually transmitted disease (STD) diagnosis and treatment (95%), Human Immunodeficiency Virus (HIV) counseling (94%), HIV testing (93%), oral contraceptive pills (89%), condoms (88%), Depo-Provera (88%), Norplant (78%), and emergency contraception (77%). Counseling, screening, pregnancy testing, and STD/HIV services were often provided on-site (range 55%-82%); contraception was often provided only by referral (on-site availability = 3%-28%). SBHCs with more provider staffing were more likely to provide services on-site; rural SBHCs and those serving younger grades were less likely to provide these services on-site. Over three-quarters (76%) of SBHCs reported prohibitions about providing contraceptive services on-site; the sources of these prohibitions included school district policy (74%), school policy (30%), state law (13%), and health center policy (12%). While SBHCs generally required parental permission for general health services, many allowed adolescents to access care independently for certain services including STD care (48%) and family planning (40%). Older SBHCs were more likely to allow independent access. CONCLUSIONS: SBHCs provide a broad range of reproductive health services directly or via referral; however, they often face institutional and logistical barriers to providing recommended reproductive health care.

Predicting smoking behaviour in census output areas across Scotland.

Spatially disaggregated surveys of smoking behaviour are rare and hence estimating the geography of the incidence of smoking is difficult. The main aim of this study is to develop a technique for estimating smoking probability for different age/sex groups in small areas across the whole of Scotland using information on smoking behaviour from the Scottish Household Survey. This is useful not only in its own right, but as an aid to studies of geographical variations in diseases such as lung cancer that, as a first step, need to control for smoking behaviour. The method developed uses individual-level characteristics from the Scottish Household Survey combined with a set of output area and pseudo-postcode sector measures from the 1991 census to model the probability of smoking. The parameters from this model are then used to make smoking predictions by age and sex for output areas across Scotland. This is the first time that such geographically detailed estimates of smoking have been made available.

Fertility decline in Scotland, England and Wales, and Ireland: comparisons from the 1911 census of fertility.

Data on family size by year of marriage, age at marriage, and duration of marriage, from the 1911 Fertility Census, are compared between Scotland, England and Wales, Irish county boroughs, and the rest of Ireland. While means show significant inter-country differences, from the 1880s marked similarities are found across all the countries in the pattern of fertility decline, strongly suggesting significant fertility limitation in rural Ireland well before 1911. Noting the implications for the use of rural Ireland as a natural fertility population, the data are instead compared with the Coale-Trussell and Hinde-Woods schedules. The former provides more plausible results, which imply strong period rather than cohort effects in the fertility decline. Except in rural Ireland, little evidence is found for significant fertility limitation early in marriage among younger marrying couples, but many older marrying couples appear to have stopped childbearing at very low parities from an early date.

A national general practice census: characteristics of rural general practices.

OBJECTIVES: The aim of the present study was to describe, using a national census, the characteristics of rural general practices and compare these with city and town general practices. METHODS: A previously piloted, anonymous but linked, questionnaire was issued to all GPs in Ireland. A liaison network covering the country was developed to increase the response rate. Respondents were asked to designate the location of their main surgery as being city (>20 000 population), town (>5000) or rural (<5000). Each responding practice was asked to nominate one partner to complete a specific section on practice information. RESULTS: Completed individual questionnaires were returned from 2093 GPs (86% response rate). Information on 1429 practice centres was provided; 488 (34%) of these were designated as city, 405 (28%) as town and 536 (38%) as rural. Rural practices reported fewer private patients (P < 0.001) and more socio-economically deprived patients (P < 0.001) than those in towns or cities. The mean number (SD) of total scheduled hours per average week per GP was 77.95 (37.0) for city practices, 80.6 (35.9) for town and 103.6 (39.0) for rural (P < 0.001). Rural practices are more likely, in comparison with those in cities and towns, to have attached staff working from purpose-built premises which are publicly owned. Rural practices also have more contacts with members of the primary care team such as Public Health Nurses, and the quality of these contacts is described more positively. The range of available services is broadly similar, with emergency medical equipment being available more frequently in rural practices. CONCLUSION: This study suggests that rural practitioners and their practices differ from their urban counterparts in many important aspects. Consideration should be given to the development of formal under- and postgraduate rural general practice programmes to prepare new, and continue to enthuse present, rural GPs.

African American grandparents raising grandchildren: a national study using the Census 2000 American Community Survey.

OBJECTIVE: The objective of this work was to determine the prevalence, sociodemographic characteristics, and service utilization patterns of African American grandparents raising grandchildren compared with noncaregiving peers. METHODS: Data were obtained from the Census 2000 Supplementary Survey/American Community Survey, a nationally representative survey of 890,000 households. Analysis was based upon comparison of 2,362 African American grandparent caregivers aged 45+ with 40,148 noncaregiving peers. Gender-specific analyses also were conducted. RESULT: Over 500,000 African Americans aged 45+ were estimated to be raising grandchildren in 2000. They were disproportionately female, younger, and less educated than noncaregivers and more likely to be living in poverty and receiving public assistance. Grandmother caregivers had significantly higher rates of functional limitations and poverty than either grandfather caregivers or other African American women aged 45+. DISCUSSION: African American grandparent caregivers, particularly grandmothers, represent a highly vulnerable population economically. The finding that four-fifths of African American grandmother caregivers below the poverty line were not receiving public assistance underscores the need for improving program outreach and substance to better serve this population. The use of theories of intersectionality and multiracial feminism in future studies of grandparent caregiving should enhance our understanding of how the impact of race on gender varies by social class.

The census-based, impact-oriented approach: its effectiveness in promoting child health in Bolivia.

This paper describes the effectiveness for child health of a primary health care approach developed in Bolivia by Andean Rural Health Care and its colleagues, the census-based, impact-oriented (CBIO) approach. Here, we describe selected achievements, including child survival service coverage, mortality impact, and the level of resources required to attain these results. As a result of first identifying the entire programme population through visits at least biannually to all homes and then targeting selected high-impact services to those at highest risk of death, the mortality levels of children under five years of age in the established programme areas was one-third to one-half of mortality levels in comparison areas. Card-documented coverage for the complete series of all the standard six childhood immunizations among children 12-23 months of age was 78%, and card-documented coverage for three nutritional monitorings during the previous 12 months among the same group of children was 80%. Coverage rates in comparison areas for similar services was less than 21%. The local annual recurring cost of this approach was US $8.57 for each person (of all ages) in the programme population. This cost includes the provision of primary care services for all age groups as well as targeted child survival services. This cost is well within the affordable range for many, if not most, developing countries. Manpower costs for field staff in Bolivia are relatively high, so in countries with lower salary scales, the overall recurring cost could be substantially less. An Expert Review Panel reviewed the CBIO approach and found it to be worthy of replication, particularly if stronger community involvement and greater reliance on volunteer or minimally paid staff could be attained. The results of this approach are sufficiently promising to merit implementation and evaluation in other sites, including sites beyond Bolivia.

Income and mortality: the shape of the association and confounding New Zealand Census-Mortality Study, 1981-1999.

OBJECTIVE: To determine the shape of the income-mortality association, before and after adjusting for confounding by other socioeconomic variables. METHODS: Poisson regression analyses were conducted on 11.7 million years of follow-up of 25-59 year old New Zealand census respondents spanning four separate cohort studies (1981-1984, 1986-1989, 1991-1994, and 1996-1999). RESULTS: Mortality among low-income people was approximately two times that among high-income people. Adjustment for potential socioeconomic confounders (marital status, education, car access, and neighbourhood socioeconomic deprivation) halved the strength of the income-mortality association, but did not appreciably change the shape of the association. Further adjustment for labour force status largely removed the income-mortality association. The association of non-transformed income with mortality was non-linear, with a flattening out of the slope at higher incomes. Both the logarithm and rank of income appeared to have a better linear fit with the mortality rate, although the association of mortality with the logarithm of income flattened out notably at low incomes. CONCLUSIONS: Much, but not all, of the crude association of income with mortality could be due to confounding. Adjusting income-mortality associations for labour force status (also a proxy for health status) is problematic: on the one hand, it over-adjusts the association as poor health will be on the pathway from income to mortality; on the other hand, it appropriately adjusts for both confounding by labour force status and reverse causation whereby income changes as a result of poor health. Both logarithmic and rank transformations of income have a reasonable linear fit with income.

Removing the health domain from the Index of Multiple Deprivation 2004-effect on measured inequalities in census measure of health.

The Index of Multiple Deprivation (IMD) 2004 is a summary measure of area-level deprivation in England that combines weighted scores in seven deprivation domains. IMD 2004 is used extensively by local public health departments and researchers to describe and monitor socioeconomic inequalities in health. However, the inclusion of a health domain in IMD 2004 leads to the possibility of 'mathematical coupling' where a relationship between IMD 2004 and markers of health is predicated by the inclusion of health in IMD 2004-effectively placing measures of health on both sides of the correlation equation. We explored the effect of removing the health domain from IMD 2004 on assignment of small areas to deprivation groups and measured inequalities in health. There was excellent agreement between the deprivation quintiles that small areas were assigned to by IMD 2004 and IMD 2004-minus-health (kappa = 0.895). Removing the health domain had little, practical, effect on measured socioeconomic inequalities in census measures of health. These findings may not hold for other measures of health, and in the context of socioeconomic inequalities in health, removing the health domain from IMD 2004 probably represents best practice.
