Temporal and spatial trends of adult mortality in small areas of Brazil, 1980–2010
To determine the variations and spatial patterns of adult mortality across regions, over time, and by sex for 137 small areas in Brazil, we first apply TOPALS to estimate and smooth mortality rates and then use death distribution methods to evaluate the ...

The deleterious mutation load is insensitive to recent population history [PDF]
Human populations have undergone dramatic changes in population size in the past 100,000 years, including a severe bottleneck of non-African populations and recent explosive population growth. There is currently great interest in how these demographic events may have affected the burden of deleterious mutations in individuals and the allele frequency ...

Mapping foreign nationals in Spain: an exploratory approach at local level
Spain, which has long been a country of emigration, has become, within a few years, one of the European countries which welcomes the most foreign nationals onto its territory.

Background: Levels and patterns of male fertility are poorly documented in developing countries. Demographic accounts of male fertility focus primarily on developed countries, and where such accounts do exist for developing countries they are mainly ...

Observed lifespan differential - global trends, policy impact and computational methods [PDF]
The issue of longevity has been long time recognized as one of key concepts in demography. A particular aspect of longevity addressed in this paper is the difference in average observed duration of life for female and male population, called observed lifespan differential.

Demography and the age of rare variants [PDF]
Large whole-genome sequencing projects have provided access to much of the rare variation in human populations, which is highly informative about population structure and recent demography. Here, we show how the age of rare variants can be estimated from patterns of haplotype sharing and how these ages can be related to historical relationships between

On the weak solutions of the McKendrick equation: Existence of demography cycles [PDF]
We develop the qualitative theory of the solutions of the McKendrick partial differential equation of population dynamics. We calculate explicitly the weak solutions of the McKendrick equation and of the Lotka renewal integral equation with time and age dependent birth rate. Mortality modulus is considered age dependent.

On the Impact of Spatial Momentum
Momentum, the population growth that occurs after a fall in fertility to replacement level, has long been appreciated as a factor in the future population growth of many countries. This paper argues that another aspect of growing populations - their high

Unravelling the progenitors of merging black hole binaries [PDF]
The recent detection of gravitational waves has proven the existence of massive stellar black hole binaries (BBHs), but the formation channels of BBHs are still an open question. Here, we investigate the demography of BBHs by using our new population-synthesis code MOBSE.

Pioneer settlement of U.S. immigrants: Characteristics of pioneer migrants and places
Background: Research on immigrant dispersion to new U.S. destinations has not addressed the question of how place and individual characteristics influence pioneer settlement.
