Postpartum amenorrhoea in rural eastern Uttar Pradesh, India.

This paper calculates the mean duration of the postpartum amenorrhoea (PPA) and examines its demographic, and socioeconomic correlates in rural north India, using data collected through 'retrospective' (last but one child) as well as 'current status' (last child) reporting of the duration of PPA. The mean duration of PPA was higher in the current status than in the retrospective data; the difference being statistically significant. However, for the same mothers who gave PPA information in both the data sets, the difference in mean duration of PPA was not statistically significant. The correlates were identical in both the data sets. The current status data were more complete in terms of the coverage, and perhaps less distorted by reporting errors caused by recall lapse. A positive relationship of the mean duration of PPA was found with longer breast-feeding, higher parity and age of mother at the birth of the child, and the survival status of the child. An inverse relationship was found with higher education of a woman, higher education of her husband and higher socioeconomic status of her household, these variables possibly acting as proxies for women's better nutritional status.

A study of aged population and associated health risks in rural India.

This article examines the prevalence of age-related diseases in different socioeconomic and demographic groups. The study is based on a sample of 267 aged persons (> 60 years) collected through a survey entitled "Aging and Health Conditions in Rural Area-A Sample Survey, 1990" conducted in the rural areas of the Varanasi district of Uttar Pradesh, a northern province of India. Various socio-behavioral factors are found to play a significant role in determining the health conditions of aged people. Also, illiteracy and poverty are found to have their own impact on health during aging. It is also noted that due to adverse familial relationships, many stress-related disorders occur which may result in the poor health of the elderly. Demands for old age pensions were made by most of the elderly people in the sample.

Population growth under changed fertility schedule in stability conditions.

"This paper aims to investigate some models for population projection under a gradual change in fertility schedule, and to evaluate integrals therein for their actual values.... Some formulae for population projection have been derived under stability conditions. The proposed formulae are also illustrated with some numerical values of the parameters involved therein. The merits and shortcomings are also discussed." (SUMMARY IN FRE)

Estimation of fecundability of migrated couples in the process of rural out-migration in India.

"Based on a simple procedure developed by Menken (1979), the estimate of fecundability of migrated couples in the process of rural out-migration [in India] has been obtained in this paper. It is found that the estimates of fecundabilities for females of different age-groups are significantly larger than the level of fecundability estimated for non-migrated couples. Some possible explanations for observing such a large gap [are] given."

Some models for patterns of urbanization, migration and development.

"This paper aims to study the pattern of urbanization and the evolution of [the] relationship between rural-urban migration and the degree of economic development taking Gross National Product...into consideration. Intercensal age-specific rural net out-migration rates are also estimated from [tabulations] of the proportion of rural population of India by age through a recently developed procedure based on generalized stable population by Stupp (1989). A comparative study is also made between [the] survival column of India with a developed nation like Japan."

On some probability models and their applications to the distribution of the number of migrants from a household.

This paper discusses some probability models in relation to their application to the distribution of the number of migrants from a household. 2 types of distribution of migrants from a household are described here: 1) male migrants aged 15 and above and 2) total number of migrants including females and children from a household. It is found that the model proposed here fitted the several sets of observed data on the number of migrants satisfactorily well.

Inter-generational occupational mobility and population heterogeneity: a statistical analysis.

"In the present paper an attempt is made to study the inter-generational occupational mobility in three types of developing villages [in India] that are heterogeneous in many socio-economic and other aspects. The specific objectives of this study are: (i) to study the overall occupational mobility of fathers-sons and to find out the predicted equilibrium structure, (ii) to find the waiting time (number of generations) that sons will stay in their fathers' occupational state before moving to other ones and (iii) to test the hypothesis of identical class structures in these three types of heterogeneous societies." The data are from a 1978 sample survey, and "the basic simple time-homogeneous Markov Chain model by Prais (1955) is employed...."
