1935, 1940, 1950, 1970
THE FOLLOWING TABLE SHOWS THE DISTRIBUTION OF SOUTHWESTERN-BORN non-Hispanic whites in California at selected dates between 1935 and 1970, the net increase in population between dates, and their representation in the population of each area. Since the sources are the Census Public Use Microdata Samples, which are one-percent census samples, the numbers are calculated estimates.
A word about the 1935 figures. They derive from the 1940 Census question, "Where did you reside April 1, 1935?" which, unfortunately, is our only source on the distribution of Southwesterners before 1940. It is not a fully accurate survey since anyone who had left California during the second half of the decade would not have been counted.
It may be noticed that there are discrepancies between this table and the data reported in some of the text tables. Table 1.1 in Chapter 1 reports volume of migration to California and includes Hispanics and nonwhites, which this table does not. The data accompanying Map 4 in Chapter 2 is not precisely comparable because it tracks persons who lived in the. South- west in 1935 as opposed to those born in those states.
