In 2007, record floods in that country killed hundreds of people, destroyed thousands of homes, and caused millions of dollars in damage. The 2020 Population Distribution in the United States and Puerto Rico map (also referred to as the 'Nighttime Map') portrays the distribution of population in the United States and Puerto Rico based on the results of the 2020 Census of Population and Housing.

The blue-to-yellow color scale was desaturated proportional to the amount of night-lights (i.e. Closely followed by China, Macao SAR with a population. The country with the highest population density was Monaco with a density of 24779.9 people per square kilometer. Unsurprisingly, these changes are happening fastest in the developing world. The map is colored to show the number of persons per square kilometer, from dark blue (1 person) to yellow (10,000 people). In the year 2020, the world had a population density of 60.1 (people/km²). Of course, this number is different depending on where you are in the globe. This map shows the population density in the United States in 2022 in persons per square mile in a multiscale map by country, state, county, ZIP Code, tract, and block group.

According to the research, the amount of light in river areas has increased 1.2 percent globally over the past 20 years. ![]() Using night lights to show both population density and economic activity, this study combined imagery from NOAA's DMSP F17 satellite with US Geological Survey maps of flood-prone areas world wide. The image above comes from a study published last month in Geophysical Research Letters that used nighttime satellite imagery to see where waterfronts are in danger. Both datasets are at a one-square-kilometre resolution. There’s a lack of information about flood risk worldwide, and it leaves people in flood-prone areas unaware of their danger, and less likely to take precautions. The population density data were generated from a gridded vector dataset of the 1992 United States census block group polygons. ![]()
