[Spatial mobility projections of the population census: comparison with other sources].

This paper considers the descriptive capacity of Italian census data on spatial mobility. A systematic comparison is carried out between the Italian census and traditional sources--particularly the population register. The discussion concerns the items collected and published as well as the measurements obtained, their meaning, and their comparability. Many examples are presented, especially on migration flows during the 1976-1981 period, as recorded by the 1981 Italian population census, applied to the whole country as well as the regions, with particular reference to the Veneto region.

Demographic trends and the pension system in Poland--a model approach.

This "article presents the results of projections of the population of Poland by age, sex and marital status till 2050 under different scenarios of fertility, mortality and nuptiality. These results are used for the analysis of future pension expenditures, the number of retirees, the labour force, and the relation between contributions and benefits. Past demographic trends and the development of social security in the post-war period in Poland are discussed as well."

Nutritional indexes of clients in a maternity and infant care project. I. The target population.

The Detroit Maternity and Infant Care Project (DMICP) is funded under Title V of the Social Security Act. Records of 198 pregnant women and their infants seen by a project nutritionist in fiscal 1971-72 were studied. The women were predominantly young (below twenty years of age), black, and not enrolled in school. Most were pregnant for the first time. About a third were overweight. Mean scores on the APGAR scale for the infants at birth were high (7 to 10). More than half of these young mothers brought their infants to the project center for check-ups six to ten times during the first year.

Stroke trends in an aging population. The Technology Assessment Methods Project Team.

BACKGROUND AND PURPOSE: Trends in stroke incidence and survival determine changes in stroke morbidity and mortality. This study examines the extent of the incidence decline and survival improvement in the Netherlands from 1979 to 1989. In addition, it projects future changes in stroke morbidity during the period 1985 to 2005, when the country's population will be aging. METHODS: A state-event transition model is used, which combines Dutch population projections and existing data on stroke epidemiology. Based on the clinical course of stroke, the model describes historical national age- and sex-specific hospital admission and mortality rates for stroke. It extrapolates observed trends and projects future changes in stroke morbidity rates. RESULTS: There is evidence of a continuing incidence decline. The most plausible rate of change is an annual decline of -1.9% (range, -1.7% to -2.1%) for men and -2.4% (range, -2.3% to -2.8%) for women. Projecting a constant mortality decline, the model shows a 35% decrease of the stroke incidence rate for a period of 20 years. Prevalence rates for major stroke will decline among the younger age groups but increase among the oldest because of increased survival in the latter. In absolute numbers this results in an 18% decrease of acute stroke episodes and an 11% increase of major stroke cases. CONCLUSIONS: The increase in survival cannot fully explain the observed mortality decline and, therefore, a concomitant incidence decline has to be assumed. Aging of the population partially outweighs the effect of an incidence decline on the total burden of stroke. Increase in cardiovascular survival leads to a further increase in major stroke prevalence among the oldest age groups.

Geophysical variables and behavior: XXIX. Impact of atmospheric conditions on occurrences of individual violence among Canadian penitentiary populations.

This project studied the effects of weather variables and size of the population on minor and major violence rates within six prisons in the Kingston, Ontario, Canada area from January, 1980 through December, 1983. While weather variables have been studied in relation to mood changes within the general population, this study was the first to analyze the impact of weather variables on rates of violence within the prison setting using forward inclusion multiple regression. Analysis showed that population size consistently appeared positively correlated with assaults on other inmates among the male medium-security prisoners during the summer months. In the summer months, temperature tended to be positively related to some minor kinds of offenses, but in the winter months the relationship was negative. Humidity, rain, sunshine hours, snow, and snow on the ground were not consistently related to incidences of minor and major violence. Indices of geomagnetic disturbances had statistically significant inverse relationships with attempted suicide/self-inflicted injury rates among the male prisoners during the summer months. Over 12 months, wind was generally negatively correlated with incidences of major and minor violence among the male inmates. For 6-mo. periods, wind was generally positively correlated with violence rates during the winter months and negatively correlated during the summer months among the male inmates. The findings relating weather variables to violence rates in the women's prison were consistently in opposition to those found for male prisoners during the 4-yr. period.

Projected number of Australians with visual impairment in 2000 and 2030.

This study aimed to project population-based prevalence data associated with visual impairment, in order to estimate the number of affected older Australians (aged 50 or older) in the years 2000 and 2030. We used data from the Blue Mountains Eye Study (BMES) and Melbourne Visual Impairment Project (MVIP), together with Australian Bureau of Statistics population projections. Similar definitions for moderate (6/24-6/60 visual acuity) and severe (< 6/60 visual acuity) visual impairment were used. Combining age-standardized data, we estimated that in the year 2000, 38 820 (0.73%) and 25590 (0.48%) Australians aged 50 years or older will have moderate and severe visual impairment, respectively. By 2030, these rates will have more than doubled, to an estimated 85910 (0.92%) and 57930 (0.62%) Australians with moderate and severe visual impairment, respectively. Women aged 50 years or older will have a 1.8-fold and four-fold risk, respectively, of moderate and severe visual impairment compared to men. Visual impairment will affect an increasing proportion of older Australians, Newer approaches to therapy, rehabilitation and community support for persons with visual impairment will be needed to meet this challenge.

[Future population growth in the Augsburg area--model calculations using the DEPOP model].

Regional population forecasts are on average even more uncertain than nationwide projections, due to the greater importance of migration and the unstable smaller absolute numbers. Other than national projections, local or regional calculations do normally have an explicit goal. In this paper, a projection of the population and age structure in the region of Augsburg is used to demonstrate some specific aspects of local population projections used for public health purposes. If institutions of childhood ages are to be projected the results are primarily determined by the assumptions on migration. If questions of old age are to be answered, the main factor of influence is the development in mortality. Depending on the specific alm of a local population projection, the principal insecurity about the future should be integrated by calculating confidence bands for those demographic parameters, that are most important for the specific question.

Projection of diabetes burden through 2050: impact of changing demography and disease prevalence in the U.S.

OBJECTIVE: To project the number of people with diagnosed diabetes in the U.S. through 2050, accounting for changing demography and diabetes prevalence rates. RESEARCH DESIGN AND METHODS: We combined age-, sex-, and race-specific diagnosed diabetes prevalence rates-predicted from 1980-1998 trends in prevalence data from the National Health Interview Survey-with Bureau of Census population demographic projections. Sensitivity analyses were performed by varying both prevalence rate and population projections. RESULTS: The number of Americans with diagnosed diabetes is projected to increase 165%, from 11 million in 2000 (prevalence of 4.0%) to 29 million in 2050 (prevalence of 7.2%). The largest percent increase in diagnosed diabetes will be among those aged > or =75 years (+271% in women and +437% in men). The fastest growing ethnic group with diagnosed diabetes is expected to be black males (+363% from 2000-2050), with black females (+217%), white males (+148%), and white females (+107%) following. Of the projected 18 million increase in the number of cases of diabetes in 2050, 37% are due to changes in demographic composition, 27% are due to population growth, and 36% are due to increasing prevalence rates. CONCLUSIONS: If recent trends in diabetes prevalence rates continue linearly over the next 50 years, future changes in the size and demographic characteristics of the U.S. population will lead to dramatic increases in the number of Americans with diagnosed diabetes.

Applicability of the Group Personality Projective Test within a prison population.

Administered the Group Personality Projective Test (GPPT) to 60 male offenders incarcerated in a state penitentiary. A board of 10 prisoners selected inmates who clearly had demonstrated one of three patterns of assaultive behavior: undercontrolled aggressives, overcontrolled aggressives, and over controlled psychopaths. A control group was chosen randomly from the prison population, as well. Results failed to support the hypothesis that GPPT scores significantly differ among relatively homogeneous prisoner subgroups or between these groups and the control group of non-assaultive prisoners.
