OCT. 28, 2021 — The U.S. Census Bureau today released the 2020 Census population and housing unit counts for the Commonwealth of the Northern Mariana Islands. As of April 1, 2020, the Northern Mariana Islands’ population was 47,329 representing a decrease of 12.2% from the 2010 Census population of 53,883. The housing unit count was 18,290 in 2020, representing a decrease of 12.3% from the 2010 Census housing unit count of 20,850.
These population and housing unit count data, as of April 1, are collected once a decade during the decennial census. The 2020 Island Areas Censuses counted people living in American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands. The Census Bureau conducts the decennial census in partnership with the Island Areas governments in compliance with Title 13 of the United States Code and to meet the specific data needs of the Island Areas.
The Census Bureau has released a set of four data tables for the Commonwealth of the Northern Mariana Islands. Tables 1 and 3 provide population and housing unit counts with numeric and percent changes for each Island Area, and the following geographies:
Tables 2 and 4 provide population and housing counts for smaller geographies, including:
The Census Bureau uses a long-form census questionnaire to meet the Island Areas’ data needs for detailed demographic, social, economic and housing unit information because other surveys, such as the American Community Survey (ACS), are not conducted in the Island Areas. This long-form census questionnaire is similar to the ACS questionnaire used in the 50 states, the District of Columbia, and Puerto Rico. Additional detailed data products will be available in the future.
“We appreciate the collaborative efforts of our Island Areas partners to complete this important count,” said Dr. Jennifer Kim, the Decennial Census Management Division's assistant division chief for Content, Translation, Puerto Rico and Island Area Operations. “Working together to provide an accurate count of the Island Areas population helps ensure that every person counts.”
