The Global Adolescent Fertility Decline is Counteracted by Increasing Teen Births in Sub-Saharan Africa.

There is a lack of understanding of the persistence of elevated teen fertility rates in certain regions and countries, in contrast to the significant decline observed in other regions globally. This report considers fertility trends among 15- to 19-year olds in the period 1950-2020 and explores potential driving factors behind the significant shifts that occurred over this period. The countries where teen fertility remains high are those with fast-growing populations, primarily located in sub-Saharan Africa.

The health-adjusted dependency ratio as a new global measure of the burden of ageing: a population-based study.

Background: The old-age dependency ratio (OADR), which is the ratio of older people (aged ≥65 years) to working age people (aged 20-64 years), is the most common way to assess and compare the burden of population ageing in different countries. However, the relationship between chronological age and dependency varies widely across countries. We therefore present the health-adjusted dependency ratio (HADR), a new measure of ageing burden based on the ageing-related health of the adult population.

A Comparative Study of Segregation Patterns in Belgium, Denmark, the Netherlands and Sweden: Neighbourhood Concentration and Representation of Non-European Migrants.

In this paper, we use geo-coded, individual-level register data on four European countries to compute comparative measures of segregation that are independent of existing geographical sub-divisions. The focus is on non-European migrants, for whom aggregates of egocentric neighbourhoods (with different population counts) are used to assess small-scale, medium-scale, and large-scale segregation patterns. At the smallest scale level, corresponding to neighbourhoods with 200 persons, patterns of over- and under-representation are strikingly similar.

Publisher Correction: Adolescence and the next generation.

In Fig. 4a of this Analysis, owing to an error during the production process, the year in the header of the right column was '2016' rather than '2010'. In addition, in the HTML version of the Analysis, Table 1 was formatted incorrectly.

Adolescence and the next generation.

Adolescent growth and social development shape the early development of offspring from preconception through to the post-partum period through distinct processes in males and females. At a time of great change in the forces shaping adolescence, including the timing of parenthood, investments in today's adolescents, the largest cohort in human history, will yield great dividends for future generations.

Religious affiliation at time of death - Global estimates and projections.

Aims: Religious affiliation influences societal practices regarding death and dying, including palliative care, religiously acceptable health service procedures, funeral rites and beliefs about an afterlife. We aimed to estimate and project religious affiliation at the time of death globally, as this information has been lacking.

Methods: We compiled data on demographic information and religious affiliation from more than 2500 surveys, registers and censuses covering 198 nations/territories.

Religious Affiliation Among Older Age Groups Worldwide: Estimates for 2010 and Projections Until 2050.

Objectives: The religious landscape of older adults around the world is changing profoundly. Yet until now, no study has chronicled these changes or compared expected aging patterns of religious groups. Differential aging among religious groups can have important economic and social consequences.
