“…It is argued that the combination of SEG and GGB might be more robust than either one individually. The combined method consists of first applying GGB to estimate any changes in census coverage (k1/k2), using the estimate to adjust one or the other census to make the two consistent, and then applying SEG using the adjusted instead of the reported population data 15,20,21 . They make several strong assumptions: (i) that the population is closed to migration; (ii) that the completeness of recording of deaths and population are constant by age; and (iii) that ages of the living and the dead are reported without error.…”

“…If there is some age x above which net migration is negligible, the performance of the methods above that age will be unaffected 15,20 . We use the age range 30+ to 65+ as suggested elsewhere 15,21 to avoid possible problems regarding migration and to overcome limitations as a result of old age reporting errors (referring to age declaration). The inverse of estimated coefficient is used to adjust the number of deaths by age and provide better estimates of mortality and life expectancy 15 .…”

Evolution of the deaths registry system in Brazil: associations with changes in the mortality profile, under-registration of death counts, and ill-defined causes of death

This paper examines the spatial pattern of ill-defined causes of death across Brazilian regions, and its relationship with the evolution of completeness of the deaths registry and changes in the mortality age profile. We make use of the Brazilian Health Informatics Department mortality database and population censuses from 1980 to 2010. We applied demographic methods to evaluate the quality of mortality data for 137 small areas and correct for under-registration of death counts when necessary. The second part of the analysis uses linear regression models to investigate the relationship between, on the one hand, changes in death counts coverage and age profile of mortality, and on the other, changes in the reporting of ill-defined causes of death. The completeness of death counts coverage increases from about 80% in 1980-1991 to over 95% in 2000-2010 at the same time the percentage of ill-defined causes of deaths reduced about 53% in the country. The analysis suggests that the government’s efforts to improve data quality are proving successful, and they will allow for a better understanding of the dynamics of health and the mortality transition.

“…O intercepto da reta estimada fornece uma estimativa da cobertura relativa entre os dois censos utilizados na análise. A análise do gráfico confirma a preocupação com a suposição de população fechada para Moçambique e em relação à qualidade na declaração de idade 6,9,17 . Os pontos em idades mais jovens para os homens são muito irregulares e fora da reta estimada.…”

“…Diversos métodos foram desenvolvidos, baseados nas equações da dinâmica populacional, para avaliar a cobertura dos óbitos em relação à população 6 . Apresentamos os métodos de forma resumida, pois há uma extensa literatura detalhando a formalização dos mesmos 3,4,5,6,8,14,15,16,17,18 . Os métodos de distribuição de óbitos são os mais comumente usados para estimar o grau de cobertura da mortalidade adulta em populações não estáveis 5,6 .…”

Resumo Os censos demográficos de Moçambique de 1997 e 2007 incluíram, em seu questionário, a pergunta sobre óbitos ocorridos no domicílio nos últimos 12 meses. O objetivo do artigo é fazer uma avaliação da qualidade da informação de mortalidade do censo para o país e suas três grandes regiões. Mais especificamente, com base em métodos demográficos formais, busca-se avaliar a qualidade da informação em termos de grau de cobertura da enumeração de óbitos e da estrutura de mortalidade, sumarizada pela probabilidade de morte entre 15 e 60 anos de idade. Em 2007, o censo enumerou entre 65 e 90% dos óbitos ocorridos em Moçambique, indicando que estimativas de mortalidade usando métodos diretos subestimam a mortalidade no país. O trabalho mostrou que há uma avanço na qualidade da enumeração da mortalidade no país e que na ausência de registros vitais de qualidade, os censos demográficos podem ser uma boa fonte de informação de mortalidade para os países em desenvolvimento.

Measuring Differential Maternal Mortality Using Census Data in Developing Countries

The 2010 census round has highlighted an increasing number of countries that have included maternal mortality in their questionnaires. Censuses have been hailed as a key source of data for maternal mortality in the absence of complete vital registration information. In particular, given the small numbers, they might be the only source of information to estimate differential mortality. This paper explores the feasibility of using census data to analyse differentials (e.g. by education and age) of maternal mortality in low-resource countries. By using data from Lesotho and Nicaragua, this study investigates the use of censuses to calculate differential maternal mortality. Methods used include indirect demographic techniques, smoothing functions, and sensitivity analysis to analyse maternal mortality by age, residence, and education. Results show that levels of adjustments vary greatly and that smoothing functions, although very useful for differential analysis, might not be powerful enough to avoid fluctuations because of small numbers. Despite the considerable investment over the last decade, results show that the census might not be a feasible tool to analyse differentials as the results suffer greatly from mortality coverage assumptions. Notwithstanding, censuses should still be considered as a key source of information and should be analysed in conjunction with other sources.

Adjusting the general growth balance method for migration

Abstract: In several countries with limited databases, studies on infant mortality are already well advanced by the various methodologies available (TIMAEUS, 1991; HILL, 2003). However, there is still much doubt regarding the estimation of mortality of adult and elderly.
