ABSTRACT
"This article investigates whether misreporting of ages contributes to the apparently low mortality at older ages in Latin America. It compares the size of cohorts enumerated at two censuses, after allowance for intercensal deaths, in 10 intercensal periods in four countries. It finds evidence of very pervasive overstatement of age at advanced ages. Using an empirical age-reporting matrix for Costa Rica, it estimates the bias that such misstatement produces in measured adult mortality levels in that country."

PIP: World Fertility Survey (WFS) data is used to study household composition in 6 countries in Latin America: Mexico, Costa Rica, the Dominican Republic, Panama, Colombia and Peru. WFS's household schedule is a census-like document that lists household members as present, absent and visitors. This issue is significant because between 10-26% of all households in Colombia, the Dominican Republic, Panama and Peru were affected; between 5-19% of the homes had an absentee member while 5-10% of the homes had a visitor. Visitors had fewer children and more young adults (15-24) than the present population. Absent members tended to be adult, males and either household heads or children of household heads. A recommendation is made to use a dejure definition that excludes visitors but includes absent members. Another critical issue in the WFS is the definition of head of household. The variation in defining this term in the 6 countries was between 66-76% because WFS classified households according to the number of couples they contained. However the Hammel-Laslett classification scheme, solitaire, no family, simple family, extended family and multiple family is recommended with WFS data. The issue of marital status is important and confusing because many of those in stable unions have never been legally or religiously sanctioned. These are counted as married. With regard to the quality of the data, Kabir's check on the internal consistency of data from 17 countries found errors in 2% (or less) of the households. A check for consistency between household and age revealed that consistency in information increased considerably when the age of groups were used in 5 year categories and not individually; 61% of those interviewed in Colombia had the same age, but when using 5 year age groups it rose to 88%.^ieng

"This paper presents six indirect techniques for estimating the degree of death coverage as applied to vital statistics information in Venezuela between 1960 and 1982, collected by two public institutions, namely, the 'Oficina Central de Estadistica e Informatica' (OCEI) and the Ministry of Health and Social Assistance (MSAS).... The results show remarkable improvements in the death registry coverage for both institutions, that amount to 97 or 98 per cent at the beginning of the 80's. Nevertheless, great differences can be observed between them regarding both structure and volume of deaths by sex and age." Among the problems discussed are the impact of immigration and errors in age reporting. (SUMMARY IN ENG)

PIP: Indirect estimation techniques for analyzing adult mortality data are presented and applied to data for Chile from 1952 to 1970. The need for corrections to inter-censal growth rates is emphasized. The impact of age misstatement on the consistency between population and death data is noted.^ieng
