Do low survey response rates bias results? Evidence from Japan

BACKGROUND In developed countries, response rates have dropped to such low levels that many in the population field question whether the data can provide unbiased results. OBJECTIVE The paper uses three Japanese surveys conducted in the 2000s to ask whether low survey response rates bias results. A secondary objective is to bring results reported in the survey response literature to the attention of the demographic research community. METHODS Using a longitudinal survey as well as paradata from a cross-sectional survey, a variety of statistical techniques (chi square, analysis of variance (ANOVA), logistic regression, ordered probit or ordinary least squares regression (OLS), as appropriate) are used to examine response-rate bias. RESULTS Evidence of response-rate bias is found for the univariate distributions of some demographic characteristics, behaviors, and attitudinal items. But when examining relationships between variables in a multivariate analysis, controlling for a variety of background variables, for most dependent variables we do not find evidence of bias from low response rates. CONCLUSIONS Our results are consistent with results reported in the econometric and survey research literatures. Low response rates need not necessarily lead to biased results. Bias is more likely to be present when examining a simple univariate distribution than when examining the relationship between variables in a multivariate model. COMMENTS The results have two implications. First, demographers should not presume the presence or absence of low response-rate biasrather they should test for it in the context of a specific substantive analysis. Second, demographers should lobby data gatherers to collect as much paradata as possible so that rigorous tests for low response-rate bias are possible

Nontraditional Family-Related Attitudes in Japan: Macro and Micro Determinants

Attitudinal data are commonly used to measure values, which in turn represent moral doctrines that are resistant to change and are the foundation for societal norms. This article examines changes in the attitudinal climate in Japan. Three national surveys (1994, 2000, and 2009) are used to examine a range of attitudes that measure a) the centrality of marriage and childbearing, b) nontraditional family behaviors, and c) gender roles in the work and family spheres. There is strong evidence of movement toward less-traditional attitudes during 1994–2000, followed by limited change in the 2000s. Period factors were paramount in the 1990s. Across the board, women hold less-traditional attitudes than men, and this difference has increased over time. Both engaging in nontraditional family behaviors (being married but remaining childless) and knowing someone who has engaged in nontraditional family behaviors (cohabitation) causally lead to holding nontraditional attitudes, suggesting mechanisms whereby changes in individual behavior can lead to changes in societal values

Employment and household tasks of Japanese couples, 1994-2009

The paper examines changes in the relationship between employment and household tasks of Japanese couples, using data drawn from national cross-sectional surveys in 1994, 2000 and 2009 of persons aged 20–49 and from the 2009 follow-up of the 2000 survey. Wives’ employment is structured by their husbands’ employment time and earning power, as well as by their family situations including the presence and age of children and coresidence with parents. Housework hours of husbands, though very low, increased over time, while wives’ hours decreased. Wives housework time decreases as their employment time increases. Marriage dramatically increases women’s housework time but produces little change in men’s time. Husbands’ housework hours are positively correlated with reported marital satisfaction of both spouses

Order amidst change: Work and family trajectories in Japan

Substantial family and work macro-level change has been occurring in Japan. Examples include a decline in the availability of jobs that afford lifetime protection against unemployment, an increase in jobs that do not carry benefits such as a pension, an increase in age at marriage and at first birth, and an increase in marital dissolution. Using life history data from the 2000 National Survey on Family and Economic Conditions, young Japanese appear to have responded to these macro-level changes in a fairly orderly manner. Marriage and childbearing have been postponed, but marriage still precedes childbearing. Education is completed prior to starting work. For men, once work commences they continue working. For women, the classic conflict between work and family roles is evident. For men and women in both the family and work spheres Japanese young adults have more orderly life course trajectories than American young adults

Identifying children with high mortality risk

For more about the East-West Center, see http://www.eastwestcenter.org/NFHS data on infant and child mortality indicate that seven groups of children in India are particularly vulnerable to mortality risks. These are: children born less than 24 months after a previous birth, children in families where an older sibling has died, children born to mothers less than 20 years old, children of illiterate mothers, children in very poor households, children in households whose head belongs to a scheduled caste or tribe, and children in households without access to a flush or pit toilet. Intervention programs to improve child survival should focus on these high-risk groups. The NFHS Bulletin is a series of four-page policy briefs summarizing secondary analysis of data from the 1992-93 National Family Health Survey (NFHS) in India. The NFHS collected information from nearly 90,000 Indian women on a range of demographic and health topics. Conducted under the auspices of the Indian Ministry of Health and Family Welfare, the survey provides national and state-level estimates of fertility, infant and child mortality, family planning practice, maternal and child health, and the utilization of services available to mothers and children. IIPS conducted the survey in cooperation with consulting organizations and 18 population research centers throughout India. The East-West Center and a U.S.-based consulting firm, Macro International, provided technical assistance, and the United States Agency for International Development (USAID) provided financial support
