We also noted that hens survival appeared to higher now than during previous decades, which suggests that perhaps a form of density-dependence is influencing wild turkey populations.

World Map » USA » USA Population Density Map. The data clearly showed that declining productivity was supported by regional declines in hens observed during summer with poults. This preserves the relative population totals across administrative units while matching the UN total. The resulting adjustment factor is multiplied by each administrative unit census value for the target year. The UN estimate for a given country (or state/territory) is divided by the total census estimate of population for the given country. However, in some areas of dense human populations, where food and cover are plentiful, turkeys have adapted and seem to survive well. The wild turkey fares better in less-disturbed areas. The tracks of an adult tom are 6 to 7 inches long adult hen tracks are 4.5 to 5 inches long.

A wild turkey may range over several square miles in one day. Experts can use this information to inform decisions around resource al location, natural disaster relief, and new infrastructure projects. Understanding and mapping population density is important. The resulting maps are the most detailed and actionable tools available for aid and research organizations. Population density is the average number of people per unit, usually miles or kilometers, of land area. Then we work with our partners at Columbia University to overlay general population estimates based on publicly available census data and other population statistics. To create our high-resolution maps, we use machine learning techniques to identify buildings from commercially available satellite images. Creative Commons Attribution International ![]()
