Combining registration-system and survey data to estimate birth probabilities.

With the widespread availability of event-history data, demographers have increasingly eschewed registration-system data in favor of survey data. We propose instead using survey and registration-system data in combination, via a constrained maximum-likelihood framework for demographic hazard modeling. As an application, we combine panel survey data and birth registration data to estimate annual birth probabilities by parity. The general fertility rate obtained from registration-system data constrains the weighted sum of parity-specific birth probabilities. The variances about the parity-specific birth probabilities are halved when registration-system data are used to constrain the estimates. Other demographic applications are discussed.

Incomplete reporting of men's fertility in the United States and Britain: a research note.

We evaluate men's retrospective fertility histories from the British Household Panel Survey and the U.S. Panel Study of Income Dynamics (PSID). Further, we analyze the PSID men's panel-updated fertility histories for their possible superiority over retrospective collection. One third to one half of men's nonmarital births and births within previous marriages are missed in estimates from retrospective histories. Differential survey underrepresentation of previously married men compared with previously married women accounts for a substantial proportion of the deficits in previous-marriage fertility. More recent retrospective histories and panel-updated fertility histories improve reporting completeness, primarily by reducing the proportion of marital births from unions that are no longer intact at the survey date.

Entry or exit? A transition-probability approach to explaining the high prevalence of single motherhood among black women.

I analyze the prevalence of single motherhood among black and non-Hispanic white women in terms of differences in entry and exit. Higher initial entry rates among black women, especially through unpartnered childbearing, account for slightly more than half the difference between blacks and whites in the prevalence of single motherhood. The remainder of the difference is due to black single mothers' much lower rates of exit through union formation and to their very high rates of reentry through dissolution of these later unions. Entry and exit rates through the 1990s imply a widening racial gap.

Aggregating poor and near-poor elderly under different resource definitions.

The large number of near-poor relative to poor elderly persons in the United States may be recharacterized as a high-prevalence, low-intensity type of poverty. The present study investigates how this characterization is affected by accounting for assets and non-cash transfers in addition to cash income in resources available for current-year consumption. The Foster, Greer, Thorbecke (FGT) poverty index is used to separately and jointly analyze prevalence and intensity of poverty. Estimation is from 1984 Survey of Income and Program Participation data. Adding the annuity value of assets removes many elderly persons from the ranks of the poor and near-poor, while adding non-cash transfers moves many elderly persons from poverty into near-poverty. Their combined effect reinforces a high-prevalence, low-intensity characterization of poverty. Large total poverty reduction effects are missed by income-only resource definition, and large poverty-intensity reduction effects are missed by prevalence-only aggregation.

Elderly poverty alleviation through living with family.

"We estimate here the extent of United States elderly poverty alleviation through living with family. These estimates are motivated by public-policy concern about the well-being of the elderly, and by the relevance of the process for fertility under the old-age-security hypothesis. An inter-temporal poverty-measurement model is estimated with 1984 Survey of Income and Program Participation income and wealth data. Without extended-family co-residence, and assuming no bequests, poverty rates would increase 42% over observed rates. Female elderly account for almost all the alleviated poverty. As a population, their impoverishment with age is effectively prevented by co-residence. Proportionately more black than white elderly are beneficiaries of poverty alleviation through living with family, but white elderly are more likely to be beneficiaries if at risk."

Cohort trends in the lifetime distribution of female family headship in the United States, 1968-1985.

We use the PSID Relationship File to estimate cohort trends in the lifetime incidence and duration of female family headship. Hazard (event-history) techniques are used to estimate movements into and out of headship, accounting for duration dependence and left-censored spells. The mean number of years spent in headship between ages 14 and 59 rose dramatically over the period. The increase arose from an increased number of headship spells, including an increase in the number of women ever experiencing headship, but not all from an increase in durations of headship spells; those decreased slightly.
