Why Do People Become Modern? A Darwinian Explanation

A procession of cultural changes, often referred to as "modernization," is initiated as a society undergoes economic development. But cultural change continues to be rapid in societies that industrialized several generations ago. Much of the change in both developed and developing societies is a progressive abandonment of the norms, values, and beliefs that encourage behavior consistent with the pursuit of genetic fitness. The kin influence hypothesis suggests that these changes are part of a cultural evolutionary process initiated by the replacement of largely kin-based communities with social groups consisting largely of non-kin. Kin have an interest in encouraging one another to behave in ways consistent with the pursuit of reproductive success, and a high level of social exchange between kin will tend to maintain norms that prescribe such behaviors. When social exchange between kin is reduced, these norms begin to relax. Cross-national comparisons of measures that reflect attitudes and behavior support the hypothesis by showing that cultural differences between countries can be substantially explained by their position on a cultural continuum that begins with social networks widening so that they become less kin-based.

Projections of the Ethnic Minority Populations of the United Kingdom 2006-2056

The ethnic minority populations in the UK are growing substantially through immigration, a youthful age structure, and in some cases relatively high fertility. Their diverse demographic and socioeconomic characteristics have attracted considerable academic and policy attention, especially insofar as those distinctive characteristics have persisted in the generations born in the UK. No official projections of the UK ethnic populations have been published since 1979. This article provides projections to 2056 and beyond of 12 ethnic groups. Given overall net immigration and vital rates as assumed in the office for National Statistics 2008-based Principal Projection, and the ethnic characteristics estimated here, the ethnic minority populations (including the Other White) would increase from 13 percent of the UK population in 2006 to 28 percent by 2031 and 44 percent by 2056, and to about half the 0-4 age group in 2056. Alternative projections assume various lower levels of immigration. Possible implications of projected changes are discussed. Copyright (c) 2010 The Population Council, Inc..
