US Census Bureau 2020 Block Groups , with total population, Hispanic and Not Hispanic population, race counts and Household counts. Used for granular inspection of population changes.
Change columns were calculated using this general approach:
2020 count minus 2010 count
Negative value in change column indicates lower count in 2020 than 2010.
Upon data review it was found that the 2010 Total Population count summarized from the calculated change table is 286 fewer than the total reported for Dallas in 2010. This is because of 104 2010 tabulation block centroids that did not intersect the 2020 Dallas tabulation blocks. Of these, 16 tabulation blocks had population counts greater than 0 and none appear to have been correctly assigned to Dallas. For the sake of population change by block, it seems safe to exclude these blocks from the calculations.
