(HRNW) The Census Bureau’s 2020 count resulted in a 5.7%, or 174,000, overcount of Puerto Rico’s population.
The overcount was discovered Tuesday after the bureau declared the end of a post-enumeration survey that was conducted independently among a sample of the island’s population to assess the accuracy of the census. The effort is being used as input for the 2030 Census upgrades.
The Census Bureau reported that over the previous ten years, Puerto Rico’s population decreased by 11.8%, to reach close to 3.3 million. But according to the most recent post-enumeration survey, Puerto Rico’s population may really be closer to 3.1 million people.
The bureau claims that issues with duplicate records may have contributed to the overcount.
Inaccurate counts were projected to have occurred at a rate of 9.8% or 319,000 during the 2020 census. Duplicate records could be responsible for nearly all of them (9.1% or 294,000), according to the study. On the American mainland, the projected rate of incorrect enumerations because of duplication is 1.6%.
