Variation in multimorbidity between and within age groups
The chronic conditions associated with age are an increasing challenge to individual and public health in many countries. In general, older age groups have a greater average multiplicity of chronic conditions (greater “multimorbidity”). But the variation (not only the average) of multimorbidity within groups of increasing age seems not to have been studied empirically. The variation in multimorbidity in groups of increasing age could, in principl…
Measuring the concentration of urban population in the negative exponential model using the Lorenz curve, Gini coefficient, Hoover dissimilarity index, and relative entropy
Stewart (1947) and Clark (1951) proposed that urban population density is a negative exponential function of the distance from a cityâ s center. This model of the spatial distribution of urban population density has been influential in urban economics, tran

Gompertz, Makeham, and Siler models explain Taylor's law in human mortality data
Taylorâ s law (TL) states a linear relationship on logarithmic scales between the variance and the mean of a nonnegative quantity. TL has been observed in spatiotemporal contexts for the population density of hundreds of species including humans. TL also de

Taylor's power law in human mortality
Taylor's law (TL) typically describes a linear relationship between the logarithm of the variance and the logarithm of the mean of population densities. It has been verified for many non-human species in ecology, and recently, for Norwayâ s human population
Is the fraction of people ever born who are currently alive rising or falling
Some journalists and demographers have asked: How many people have ever been born? What is the fraction F(t) of those ever born up to calendar year t who are alive at t? The conditions under which F(t) rises or falls appear never to have been analyzed
Life expectancy
We give simple upper and lower bounds on life expectancy. In a life-table population, if e(0) is the life expectancy at birth, M is the median length of life, and e(M) is the expected remaining life at age M, then (M+e(M))/2≤e(0)≤M+e(M)/2
Determinants of International Migration Flows to and from Industrialized Countries
We quantified determinants of international migratory inflows to 17 Western countries and outflows from 13 of these countries between 1950 and 2007 in 77,658 observations from multiple sources using panel-data analysis techniques. To construct a quantitative model that could be useful for demographic projection, we analyzed the logarithm of the number of migrants (inflows and outflows separately) as dependent variables in relation to demographic,…

Life expectancy is the death-weighted average of the reciprocal of the survival-specific force of mortality
The hazard of mortality is usually presented as a function of age, but can be defined as a function of the fraction of survivors. This definition enables us to derive new relationships for life expectancy. Specifically, in a life-table population with
Constant global population with demographic heterogeneity
To understand better a possible future constant global population that is demographically heterogeneous, this paper analyzes several models. Classical theory of stationary populations generally fails to apply. However, if constant global population siz

Should Population Projections Consider "Limiting Factors"--and If So, How
Population questions have dimensions scales and purposes. It is noted that whether and how population projections should consider limiting factors depend on the dimensions scales and purposes of the projections. In addition to demographic and social aspects dimensions of population questions include economics the environment and the culture. Possible constraints of food and water are likely to be mediated through economic and political systems; h…
How Many People Can the Earth Support
This article offers an overview of global human population economy environment and culture in order to explain why some people are interested in the question How many people can the Earth support? The article reviews some answers to the question and suggests ways that could alleviate some of the problems of population economics environment and culture. The author reiterates that population problems are not purely demographic but also involve econ…
The role of the peridomiciliary area in the elimination of Triatoma infestans from rural Argentine communities
The purpose of this study was to identify the origin of Triatoma infestans reinfestation and study its dynamics following spraying with deltamethrin inside and around 94 houses in three rural communities in northwestern Argentina. The effectiveness of the spraying was evaluated immediately after the houses were sprayed and two months later. In addition, five residual peridomiciliary foci were found and sprayed, as well as three preexisting ones t…
State legislators' attitudes and voting intentions toward tobacco control legislation
OBJECTIVES: This study describes state legislators' knowledge, attitudes, and voting intentions with regard to tobacco-related issues. METHODS: A cross-sectional survey of state legislators was conducted in North Carolina, Texas, and Vermont in 1994. RESULTS: Most legislators agreed that secondhand smoke can cause lung cancer in nonsmokers, and a majority believed that smokers are addicted to nicotine. More than 75% stated that they would support…
Why Should More United States Tax Money be Used to Pay for Development Assistance in Poor Countries
The author briefly discusses the question should more United States tax money be used to pay for development assistance including population assistance in poor countries?...My question then breaks into two questions. First how would American interests be advanced by more rapid development or harmed by less rapid development in poor countries? Second why is taxing me to pay for U.S. government development programs a more effective way to promote d…

Population Growth and Earth's Human Carrying Capacity
Earth's capacity to support people is determined both by natural constraints and by human choices concerning economics, environment, culture (including values and politics), and demography. Human carrying capacity is therefore dynamic and uncertain. Human choice is not captured by ecological notions of carrying capacity that are appropriate for nonhuman populations. Simple mathematical models of the relation between human population growth and hu…

Population forecasts and confidence intervals for sweden
This paper compares several methods of generating confidence intervals for forecasts of population size. Two rest on a demographic model for age-structured populations with stochastic fluctuations in vital rates. Two rest on empirical analyses of past forecasts of population sizes of Sweden at five-year intervals from 1780 to 1980 inclusive. Confidence intervals produced by the different methods vary substantially. The relative sizes differ in th…
Childhood Mortality, Family Size and Birth Order in Pre-Industrial Europe
Based on parish registers, demographic histories of Crulai (France), Tourouvre-au-Perche (France), and Geneva (Switzerland) established the childhood mortality experienced by complete sibships during periods of at least half a century before the French revolution. These observations may be presented as frequencies in incomplete five-dimensional contingency tables. The five dimensions are: survival (living or dead), completed sibship size, birth o…
