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. Two versions of this dot distribution map are available: a large format map and a small format map. On the large format or wall map version (which measures approximately 28 x 24 inches), each white dot represents 1,000 people. On the small format or page size version (which measures 11 x 8.5 inches), each white dot represents 7,500 people.
