Oftentimes, in rural regions with low population density, large census tracts are home to a small number of people. Mapping population distribution by census tract can misrepresent population density. Source imagery for HRSL © 2016 DigitalGlobe. This fact sheet reports the population distribution for the 687 census tracts in the State of Nevada between 20. Expand any category (e.g., Population, Families and Households, Housing) for a list of maps.

The resulting adjustment factor is multiplied by each administrative unit census value for the target year. Its most populous states are California with a population of 39.5 million and Texas with a population of 28. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the 'urban footprint. By population, the United States of America is the 3rd largest country in the world, behind China (1.39 billion) and India (1.31 billion). One of the main drivers of the faster population growth in Northern Ireland is the comparatively high level of natural change driven by a younger population (median age of 38.9 years compared with 40. The UN estimate for a given country (or state/territory) is divided by the total census estimate of population for the given country. United States Area and Population Density. In the 12 months to mid-2019, the population of Northern Ireland grew by 0.6 while that of the UK as a whole grew by 0.5.

The resulting maps are the most detailed and actionable tools available for aid and research organizations. 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
