1960 Census of Population: Supplementary Reports: Population of the United States, by Single Years of Age: 1960

Report Number PC(S1)-32

The tables presented here are preprints of tables 156 and 270 (or portions thereof) from Final Report PC(1)-lD, which contains additional summary information on the detailed characteristics of the population.

Statistics on the distribution of the population by single years of age reflect past trends in births, deaths, and migration. Thus, in 1960 the fact that there were fewer native persons in the single years between 30 and 39 reflects the smaller number of births in the decade 1930-40 than in the decade 1920-30. Even though the persons born between 1920 and l 930 had been exposed to mortality for an additional l0-year period, the number of survivors was larger because there had been more births in the earlier period.

Among the foreign born, the high concentration in the single years between 60 and 69 years reflects the heavy immigration of young adults in the period between the end of World War I and the passage of the Immigration Act of 1924. After the quota system was established, the annual number of immigrants became much smaller and, therefore, there are relatively moderate numbers in the single years at the younger ages.

Although single-year-of-age data do provide a detailed record of past demographic trends, they also provide evidence as to the difficulties of obtaining accurate age data. The use of a question on date of birth rather than on completed years of age as a source of data on age was expected to change the extent and nature of misreporting of age in the 1960 Census from those occurring in earlier censuses.

A Note on Language

Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
