Inconsistent Respondents and Sensitive Questions

This article focuses on respondents as the source of measurement error, regardless of the question being asked, interviewer effects, or other factors that influence survey quality. Some individuals simply provide poorer answers as a result of a behavior called satisficing. An especially troublesome case is that of sensitive questions, where misreporting is common. In the study reported here, a significant role was found for individual-level time consistency as a predictor for answers to sensitive questions related to children, sex, condoms, and HIV. Couples’ reports, where couple-level fixed effects (including the “true” answer) can be ruled out, confirm this result. Satisficing may have more of an impact on how individuals respond to sensitive questions than previously thought.

LATE-ENTRY-INTO-MOTHERHOOD WOMEN ARE RESPONSIBLE FOR FERTILITY RECUPERATION

In countries where age at parenthood has shifted to older ages, a necessary precondition for fertility recuperation is that women having their first child later in life (after age 30) will also eventually achieve a higher completed fertility, compared with the previous cohorts. This study analysed the changes in age-at-first-child-conditional fertility rates in Western Europe through three birth cohorts (1936–1940, 1946–1950 and 1956–1960). It was found that generations where recuperation is first evident (1956–1960 cohort) are characterized by comparatively higher fertility of late age-at-first-child women. This characteristic is not found in Eastern Europe, where ages at first birth and cohort fertility remained fairly constant across the cohorts analysed.

The evolution of the socioeconomic gap in fertility among adolescents in Chile, 1990-2011

For research and policy issues, it is very important to measure the evolution of socioeconomic differences in the adolescent fertility rate over time (AFER) in order to be able to provide a quantitative description of such an evolution. By combining well reputed Chilean data, this study computes a ratio of AFER (15-17 years-old) between the 30% of the population living in economically worst off areas (the numerator) against the corresponding 30% better off segment of the population (the denominator). This ratio of AFER by relative socioeconomic status shows a stable evolution from 1.45 in the year 1990 to 1.10 in 2011. Sexual initiation, whose association with AFER is well established, also shows a dropping ratio, from 1.24 in 1997 to 1.01 in 2012. The size of some dimensions of socioeconomic inequalities in adolescent fertility and sexual initiation has being decreasing between 1990 and 2011. This exercise shows that even in Chile, the most unequal country among the Organisation for Economic Co-operation and Development, there are some improvements in health inequality.

Inequality in mortality decreases with age: evidence from developing countries using census data

With some exceptions, studies consistently find that mortality rate ratios between the highest and lowest socioeconomic status (SES) groups are substantially larger among the young-age population, rather than the old one. This pattern is relevant for policy and research, but it has seldom been explored in populations of developing countries. In this study, eight samples in the Integrated Public Use Microdata Series (IPUMS) that contain mortality data (El Salvador 1992, Rwanda 2002, Senegal 2002, Sierra Leone 2004, Uganda 2002, Malawi 2008, Brazil 2010, and Zambia 2010) and information about household assets are analyzed, and, using SES of equal relative size, results in seven out of eight cases are the same as those in developed societies: ratios are larger among the young age group and among men. Therefore, the ratio of mortality by relative-SES also decreases with age in several developing ones.

The role of answering behaviours on weight misreporting.

BACKGROUND Biases in self-reported weight are very common among young adults and adults. Although social norms are the most commonly accepted explanation for these misreports, corresponding evidence is scarce and conflict-ridden. An alternative explanation for biases in weight self-reports comes from answering behaviours; non-random rounding, formally an answering behaviour, has been found to play a significant role in several studies of weight misreporting. However, the presumably rich role of answering behaviours has seldom been explored. This study brings a second answering behaviour into the analysis: inconsistency. METHODS An inconsistency index was computed as an individual-level score from several questions across waves in the National Health and Nutrition Examination Survey. By regression analysis (N=3480 men and 1856 women) the simultaneous role of inconsistency and of non-random rounding on weight misreporting was explored. RESULTS Inconsistency was found to be associated with higher self-reported weights. Inconsistent individuals provided significantly different misreports, with women under-reporting 0.23[kg] (0.01-0.45) less and men over-reporting 0.42[kg] (0.02-0.82) more than their consistent counterparts. Inconsistency was found to play a simultaneous and substantially larger role than non-random rounding. This result was clearer among men than it was among women. DISCUSSION Although social norms are usually thought to be the central explanation of weight-biased misreports, there are other factors, such as answering behaviours, that might play a more influential role.
