Hunter-gatherer economic complexity and “population pressure”: A cross-cultural analysis

This paper examines the relaionship between “population pressure” and socioeconomic complexity among hunter-gatherers. Population pressure is defined as the ratio between population density and the density of available resources. Socioeconomic complexity is measured by means of several correlated variables: storage-dependence, sedentism, social inequality, and use of a medium of exchange. Correlations between these variables are calculated from an ethnographic sample of 94 hunter-gatherer groups. The correlations between population pressure and socioeconomic complexity are found to be extremely high. Two major types of hunter-gatherers exist which are distinguished by a number of variables and may be termed “simple” and “complex.” Transitional groups between these two types are quite rare. It is also noted that population pressure does not arise in continental climates where famine mortality is common because of high-amplitude changes in productivity from year to year. It is argued that population pressure is a necessary and sufficient condition for and the efficient cause of socioeconomic complexity. The widespread disavowal by archaeologists of population pressure as a possible explanation for the prehistoric development of complex hunter-gatherers has no basis in ethnographic fact.     

Latino political participation in the Texas Panhandle, 1980–2010

Since the institution of the Bracero Program in 1942, Latinos (mostly Mexicans) journeyed to the United States in search of temporary manual labor. This economically driven migration continued after the termination of the Bracero Program in 1964 as Latinos from Mexico and South Texas searched for employment opportunities. The Latino population in the Texas Panhandle grew from 173,000 in 1980 to 340,000 in 2010. This new Latino population settled in counties that were predominantly Anglo and replaced some of the departing Anglos who looked for better jobs, mainly in the Dallas–Fort Worth Metroplex. This substantial shift in the ethnic composition of the region’s population resulted in a restructuring of the labor market and notable imprints to the cultural landscape. Over the years, Latinos have slowly begun to participate in city and county politics. This quantitative study investigated the impact of Latino migration and population increase on Latino political participation in the Texas Panhandle.
