  Background: Earlier investigations have shown mortality effects of community socioeconomic resources. However, the sex differences have not been clear and the estimates may well have been biased because of inadequate control for community factors affecting both the socio-economic resources and mortality. The objective of this study was to see whether effects appeared when time-invariant community characteristics were controlled by including community dummies (fixed effects) and whether there were differences between women and men. Methods: Discrete-time hazard models for all-cause mortality were estimated for 1981-2002 for all Norwegians aged 60-89, using register data. There were 730000 deaths among 1.7 million people observed during 19 million person-years. Average education was measured for 433 municipalities for each of the 22 years. Results: According to the simplest models, a high average education in the municipality is associated with increased mortality. Control for population size (timeaveraged) reversed the effects. Inclusion of municipality dummies instead of population size, to control also for additional unobserved time-invariant municipality characteristics, gave very different results: the effects were even stronger for men, while those for women were no longer significant. The results were quite robust to alternative specifications, including the use of a lagged average-education variable. Conclusion: The study supports the idea that community socio-economic resources may affect mortality and suggests that sex differentials may deserve more attention. It also illustrates the importance of controlling for time-invariant community factors. Unless these can be easily measured, one may in future investigations consider establishing longitudinal data and use a fixed-effects approach such as here.

  Many researchers have shown an association between a person's health or mortality and the socio-economic resources in the community, net of the person's own resources. The focus has typically been on the current community of residence or one where the person lived a few years earlier. Only a few authors have tried to establish whether there is an additional effect of earlier community exposures, and they have not made a distinction between migrants and non-migrants, which there are good reasons to do. The results from these earlier investigations have been rather mixed. In the present study, a discrete-time hazard model for mortality between ages of 60–89 over the period 1991–2002 was estimated from register data that included the entire Norwegian population. For each person, and for each of these years, municipalities of residence during the previous 20 years were known. There was also information on each person's educational level. For the relevant years and each of the 433 municipalities, measures of average education in the population were constructed by aggregating over the individual data. The analysis was focused on the subgroup who had moved across a municipality border only once during the previous 20 years, among whom there were 29,843 deaths during 839,113 person-years of follow-up. The population sizes of the municipalities were included as control variables. Among those who had moved within the last 10 years, the current socio-economic context was not important for mortality. The earlier context had an effect, but this was restricted to men. Those who had lived longer in the current municipality of residence were influenced only by the average education in that municipality. The findings support the idea that neighbourhood socio-economic effects need some time to build up, and that they do not dissipate soon after the person has moved to a new environment.

  When assessing the importance of education for fertility, one should ideally use complete education histories. Unfortunately, such data are often not available. It is illustrated here, using register data for Norwegian women born in 1969, that inclusion of educational level at the latest age observed (28), rather than at the current age, can give substantially biased education effect estimates. It is also illustrated that imputation of education for earlier ages may lead to wrong conclusions. A simple imputation of educational level and enrolment based on the assumption that everyone passes through the educational system with the officially stipulated progress gives particularly misleading results. Somewhat better estimates are obtained when a slower progress more in accordance with reality is assumed, or when educational level and enrolment are imputed stochastically on the basis of distributions calculated from real data. Obviously, one should be very careful when faced with incomplete education histories, and try to make use of relevant information, from other sources, about the actual educational careers.

  Study objectives - Sociodemographic differentials in cancer survival have occasionally been studied by using a relative-survival approach, where all-cause mortality among persons with a cancer diagnosis is compared with that among similar persons without such a diagnosis (¿normal¿ mortality). One should ideally take into account that this ¿normal¿ mortality not only depends on age, sex and period, but also various other sociodemographic variables. However, this has very rarely been done. A method that allows such variations to be considered is presented here, as an alternative to an existing technique, and is compared with a relative-survival model where these variations are disregarded and two other methods that have often been used. Design, setting and participants ¿ The focus is on how education and marital status affect the survival from twelve common cancer types among men and women aged 40-80. Four different types of hazard models are estimated, and differences between effects are compared. The data are from registers and censuses and cover the entire Norwegian population for the years 1960-1991. There are more than 100 000 deaths to cancer patients in this material. Main results and conclusions - A model for registered cancer mortality among cancer patients gives results that for most, but not all, sites are very similar to those from a relative-survival approach where educational or marital variations in ¿normal¿ mortality are taken into account. A relative-survival approach without consideration of these sociodemographic variations in ¿normal¿ mortality gives more different results, the most extreme example being the doubling of the marital differentials in survival from prostate cancer. When neither sufficient data on cause of death nor on variations in ¿normal¿ mortality are available, one may well choose the simplest method, which is to model all-cause mortality among cancer patients. There is little reason to bother with the estimation of a relative-survival model that does not allow sociodemographic variations in ¿normal¿ mortality beyond those related to age, sex and period. Fortunately, both these less data demanding models perform well for the most aggressive cancers.

  Using DHS data for 22 countries in Sub-Saharan Africa, it is found that average educational level in the community (DHS cluster) has a significant depressing effect on a woman's birth rates, net of urbanization and her own education. According to simulations, average fertility for these countries would be 1.00 lower if education were expanded from the current level in the region to the relatively high level in Kenya. Exclusion of aggregate education from the model leaves a response of only 0.52. A considerable aggregate contribution is estimated even when several potential determinants of education are included. This illustrates the need to consider aggregate education in future assessments of the total impact of education.

  According to models estimated separately for second-, third-, and fourth-birth rates in Norway, an increase took place from the mid-1970s to about 1990, given age and duration since last previous birth. A similar rise in the birth rates was seen in Sweden, except that the upturn at short durations was sharper. It is shown in this study, using Norwegian register data, that the increase partly reflects earlier changes in lower-order parity transitions. When models for each parity transition are estimated jointly, with a common unobserved factor included, there is no longer an upward trend in Norwegian second-birth rates, but a very weak decline, and the increase in the higher-order birth rates is strongly reduced compared to that found in the simpler approach.

  Continuous-time hazard models are estimated from register-based birth, migration, education and unemployment histories for the complete Norwegian population, linked with aggregate data for municipalities. The analysis covers the period 1992-98. First-birth rates are slightly higher among women who had been unemployed twelve months before than among others, whereas higher-order birth rates are slightly lower. Although men¿s unemployment has a more pronounced negative effect, according to paternity rate models, the overall conclusion is that unemployment in Norway has had a negligible impact on fertility through individual-level effects. Aggregate-level effects are more important. Higher-order birth rates are lower in municipalities where men¿s or women¿s unemployment is high than elsewhere. All in all, the peak unemployment level of 6% experienced in 1993 is found to be associated with a reduction of about 0.08 in total fertility. The results accord well with economic theories for first and higher-order births that are based on the assumption that women are still the primary caretakers.

  It is estimated, on the basis of data from FAO and some other sources, that high population growth in countries with an initial average calorie intake below 2800 has contributed to inhibit improvements in per capita food production and availability during the 1980s and early 1990s. There are statistically significant negative effects of population growth on the growth in noncereal food crops, milk and meat production, and total food production. Because also net food import and aid shipments of cereals have responded similarly, rather than being compensatory factors, the development in total per capita calorie supply has been least satisfactory in countries with the most rapid growth. A rapid increase among adults appears to be no less disadvantageous than an increase among young or elderly. Weaker effects are found when the entire 1970-95 period is considered. There are few indications that poverty, illiteracy or land or water scarcity have made it particularly difficult to cope with a growing population.
