Data in the table were developed by the Census Bureau. Values showing "below 500" were converted to the numeric value 499. The value 499 represents change values from -499 to 499. When a change value is in this range, the value 499 appears in the table. When 499 appears in the change value, all that can be determined from the table is that the true value is in the range -499 to 499.

In general, it is possible to compute the population for any decennial census date by starting with the Census 2010 population and subtracting gains and adding losses, except for the 499 values which might be treated as zero (but will likely yield a factually inaccurate number).

Example. Copy the Harris County, TX row to clipboard. Paste into cell A1 of an Excel spreadsheet.
Set cell O2 to D2-SUM(E2:N2). The computed total population for Harris County, TX as of the 1910 Census is 115,693.
