Notes
1940 Census
The original 1940 Census reports show the population of the town of Atkinson as 343. Tables in the 1950 and 1960 reports indicate that Atkinson’s 1940 population was 434, however. As 434 adds correctly to the county total and 343 does not, 434 appears to be correct, and the occurrence of 343 in the 1940 reports seems to have been a typo.
1960 Census
The Census Bureau made a number of revisions to 1960 census totals subsequent to their initial release. When it did so, however, it appears to have updated municipal totals only, not overall county totals or state totals, even though in most cases changing municipal totals should have caused county and state totals to change. The 1960 total for Rockingham County was originally reported as 99,029; for the city of Portsmouth, 25,833; and for the town of Newington, 2,499. The totals for Portsmouth and Newington were later revised to those shown in the list above (26,900 and 1,045). This should have caused the county total to change as well (to 98,642), but subsequent census publications have continued to list the county total as it was originally reported (99,029). As a result, in the list above, the municipal totals for 1960 do not add to the county total. The 1960 state total for New Hampshire that appears in various Census materials (606,921) likewise reflects the original 1960 total for Rockingham County and does not take into account the revisions made to the population of Portsmouth and Newington.
