![]() ![]() The National Identifier Grid was reprocessed to remove artifacts from inland water.The netCDF files were updated to include the Mean Administrative Unit Area layer, the Land Area and Water Area layers, and two layers indicating the administrative level(s) of the demographic characteristics input data.Erroneous no data pixels in all of the gridded data were recoded as 0 in cases where census reported known 0 values.The extent of the final gridded data has been updated to a full global extent.In this release, several issues identified in the 4.10 release of December 2017 have been corrected as follows: The nine data sets of the current release are collectively referred to as the Revision 11 (or v4.11) data sets. GPWv4 is gridded with an output resolution of 30 arc-seconds (approximately 1 km at the equator). The raster data sets are constructed from national or subnational input administrative units to which the estimates have been matched. A set of estimates adjusted to national level, historic and future, population predictions from the United Nation's World Population Prospects report are also produced for the same set of years. The input data are extrapolated to produce population estimates for the years 2000, 2005, 2010, 2015, and 2020. ![]() It provides globally consistent and spatially explicit data for use in research, policy-making, and communications.įor GPWv4, population input data are collected at the most detailed spatial resolution available from the results of the 2010 round of Population and Housing Censuses, which occurred between 20. The purpose of GPW is to provide a spatially disaggregated population layer that is compatible with data sets from social, economic, and Earth science disciplines, and remote sensing. Since the release of the first version of this global population surface in 1995, the essential inputs to GPW have been population census tables and corresponding geographic boundaries. 100-300, Massachusetts, Connecticut, Maryland, Delaware, New York, Florida, Ohio, Pennsylvaniaįor premium maps of US counties by state, please visit our Gridded Population of the World (GPW) collection, now in its fourth version (GPWv4), models the distribution of human population (counts and densities) on a continuous global raster surface.300+, District of Columbia, Rhode Island, New Jersey, Puerto Rico,.Slide 3 US Population Density Map 2020 -2įrom the perspective of People per square kilometer, that is the state population divided by the land area, it is 36 people per square kilometer for the whole country. 100-200, Indiana, Georgia, Michigan, South Carolina, Tennessee, New Hampshire, Washington, Kentucky, Texas, Wisconsin, Louisiana.200-500, New York, Florida, Pennsylvania, Ohio, California, Illinois, Hawaii, Virginia, North Carolina.500+, District of Columbia, New Jersey, Rhode Island, Massachusetts, Puerto Rico, Connecticut, Maryland, U.S.It is obvious that most populated states concentrated in the northeast New England ones. Slide 2 US Population Density Map 2020 -1įrom the perspective of People per square mile, that is the state population divided by the land area, it is 94 people per square mile for the whole country. Other states with 10 million are Pennsylvania, Illinois, Ohio, Georgia, North Carolina and Michigan. From the chart below you can see that California has been the most populated state with 39.5 million populations, while Texas, Florida and New York states occupied the top four with populations over 20 million. The US population has been recorded for 331,449,281. Slide 1, US Population Density Heat map 2020Ģ020 is the twenty-fourth decennial United States Census, which began on April 1 st 2020. As the US diagram PowerPoint template series, you can also enjoy 50 US State Shapes Map Template, United States Maps template, United States Map template, and US regions map. Finally is the population density of People per square kilometer. Secondly is the population density of People per square mile. Firstly we have the diagram to show the total population levels by state. The US population density maps Template in PowerPoint format include three slides. ![]()
