Urban settlement size trends in the former USSR: 1970-1989.

"Based upon recently published data, this paper investigates urban settlement size trends in the former USSR and its republics during the intercensal periods of 1970-1979 and 1979-1989. Results indicate that although a trend toward largeness of the Soviet urban hierarchy continues, a slowing in this direction has occurred. Among republics, all had an increasing trend towards largeness on at least one and usually all three summary measures of urban settlement size structure. The RSFSR [Russia] and Armenia especially consistently evidenced a relatively high degree of largeness, while the former Baltic republics generally revealed a relative smallness."

Comparison of ward population estimates from FHSA patient registers with the 1991 Census.

"Postcode addresses from National Health Service patient registers for Norfolk and Suffolk [counties in England] current on census day 1991 were assigned to census wards, and estimates of populations in wards were produced for the total population and for twelve age-sex groups. These were compared with adjusted counts of usual residents from the 1991 Census." The results indicate that family health service authority registers "are an acceptable alternative to the census for population estimation purposes. This supports recent arguments for wider use of population registers and suggests that they may be particularly valuable as a source of intercensal information."

Adjusting craniofacial correlations for technical error.

Reliability estimates provide a means of adjusting observed correlations for technical error. The results show that the true correlations among 11 craniofacial landmarks are consistently higher than observed values. Consequently, the regression slopes defining these relationships are also increased. The less reliable two measures are, and the closer their joint reliability approximates the observed correlation, the greater the expected change in true correlation. Adjusting craniofacial relationships for technical error may substantially increase the proportion of variation explained, and thereby alter statistical inferences drawn from results.

Nuptiality models and the two-sex problem in national population forecasts.

"This paper describes the two-sex problem in nuptiality models, focussing on applications in national population forecasts. Requirements for a realistic two-sex marriage model are mentioned, together with additional considerations important in the context of official forecasts. Recent nuptiality models violate the requirements to a certain extent and/or do not meet the additional considerations. A new model, used in the 1980-based population forecasts of the Netherlands compiled by the Netherlands' Central Bureau of Statistics, is described." (summary in FRE)

Estimating proximate populations for an extensive set of locations in Australia.

"The paper reports the use of Australian Resources Information System to calculate two proximate populations (people living within (i) 150 and (ii) 500 km) for the centroids of each of 3,000 half by half degree geodetic grid cells covering Australia. The use of proximate population data is exemplified by computing a map of the eighteen regions collectively containing a maximum fraction of the Australian population." The data used are from the 1981 census.

Using remotely sensed data for census surveys and population estimation in developing countries: examples from Nigeria.

"Using examples from Nigeria, this paper demonstrates how remotely sensed data can be used to acquire some of the basic data requirements for census surveys and to estimate population. The result obtained shows that visual identification of settlements on Landsat MSS and TM is more accurate and economical than equivalent digital classification techniques. Black and white aerial photographs were used to estimate the population of a model town and to establish EAs [enumeration areas]. The population estimation method employed can be used to obtain intercensal population estimates for the rapidly growing central places, while the established EAs for the study area have created a permanent base for future census surveys and census cross-validation, population estimation and other social surveys."

[Population of Southeast Asia in the mid-nineteenth century: population counts appearing in the Journal of the Indian Archipelago and Eastern Asia].

"This paper aims to compile and evaluate the information on the population of Southeast Asia in the Mid-nineteenth century appearing in the Journal of the Indian Archipelago and Eastern Asia, which was published from 1847 to 1860 in Singapore. The journal contains considerable numbers of population figures for the pre-census period,...[concerning] Sumatra, the Malay Peninsula, the Straits Settlements, Java, Bali, Lombok, Sulawesi, Borneo, and other parts of insular Southeast Asia. The general tendency of the population counts of insular Southeast Asia in this period by the Europeans is toward underestimation. This is especially true for the inland areas of the larger islands, which were remote from the European sphere of influence. Populations of the small islands located on commercial routes are reported relatively accurately or even overestimated. Populations of the European settlements are sometimes overestimated and their growth rates tend to be exaggerated." (SUMMARY IN ENG)
