Surnames in Bolivia: A study of the population of Bolivia through isonymy.
Summary of "Surnames in Bolivia: A study of the population of Bolivia through isonymy."
In Bolivia, the Hispanic dual surname system is used. To describe the isonymic structure of Bolivia, the surname distribution of 12,139,448 persons registered in the 2006 census data was studied in 9 districts and 112 provinces of the nation, for a total of 23,244,064 surnames. The number of different surnames found was 174,922. Matrices of isonymic distances between the administrative units (districts and provinces) were constructed and tested for correlation with geographic distance. In the 112 provinces, isonymic distances were correlated with geographic distance (r = 0.545 +/- 0.011 for Euclidean, 0.501 +/- 0.012 for Nei's, and 0.556 +/- 0.010 for Lasker's distance). The multiple regression of the surname effective number (alpha), equivalent to the allele effective number in a genetic system, was nonsignificant on latitude and longitude; however, it was highly significant and negative on altitude (r = -0.72). Because the Andes extend from north to south in west-central Bolivia, random inbreeding was lowest in the eastern districts, and highest in mountainous western Bolivia. Average alpha for the provinces was 122 +/- 2; for the districts, it was 216 +/- 29, and for the whole of Bolivia it was 213. The geographical distribution of alpha in the provinces is compatible with the settlement of subsequent groups of migrants moving from east and north toward the center and south of Bolivia. The relative frequency of indigenous surnames is correlated positively with altitude. This suggests that the country was populated by recent low-density demic diffusion over a low-density indigenous population. This may have been a common phenomenon in the immigration to tropical South America. Am J Phys Anthropol, 2010. (c) 2010 Wiley-Liss, Inc.

Medical and Biotech [MESH] Definitions
Callithrix
A genus of the subfamily CALLITRICHINAE occurring in forests of Brazil and Bolivia and containing seventeen species.
Names
Personal names, given or surname, as cultural characteristics, as ethnological or religious patterns, as indications of the geographic distribution of families and inbreeding, etc. Analysis of isonymy, the quality of having the same or similar names, is useful in the study of population genetics. NAMES is used also for the history of names or name changes of corporate bodies, such as medical societies, universities, hospitals, government agencies, etc.
Population Surveillance
Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.
Sentinel Surveillance
Monitoring of rate of occurrence of specific conditions to assess the stability or change in health levels of a population. It is also the study of disease rates in a specific cohort, geographic area, population subgroup, etc. to estimate trends in larger population. (From Last, Dictionary of Epidemiology, 2d ed)
