    BIRTHPLACE Place of birth was obtained from the question, ''Where were you born? In the United States or in some other country. United States residents were asked, ''Which city and state?'; all others wereasked, Which coun- try?(Question 18, Appendix A-II) As is well known, Californians are largely migrants and a relatively small proportion of the sample were born in California. Eighty-seven percent of the total sample were born in the United States but the area of their birth differed greatly by race. (Table 17, Appendix B) Fifty-six percent of other'' nonwhite races, pre- dominantly Orientals, were foreign born; only twenty-five percent of them were born in California. A third of the white persons were California born but only six percent of Negroes were born in California. The Ne- groes were predominantly from the South Central area (77 percent). RESIDENTIAL STABILITY Californians are known for their residential mobility; the population of any California city or area contains a high proportion of relatively recent arrivals. The residential stability of Alameda County residents was ex- amined in terms of the number of years they had lived in their present town or city.(Table 18, Appendix B) This was obtained from the residen- tial history items. Forty percent of the study population had lived in their present town or city five or less years. However, there was a large pro- portion of stable old-timers too; 44 percent had lived 11 or more years in their current city or town. Negroes were more Stable than the whites. Fifty-six percent of the Negroes had lived eleven or more years in their current city or town. SUMMARY In this section the nature of the study population has been described in terms of family income, education and occupational levels. Most of the sample population were married, had children, and were born outside of California. The mobility of the sample was manifested by the large pro- portion who lived in their current place of residence five years or less; however, there was also a large proportion of residentially stable persons. Considering all of these social and demographic factors, a wide spread has been shown reflecting the socially heterogeneous nature of the sample population. The Negro group in the sample was also heterogeneous. Although the majority was born in the South and was at the lower educational, occupa- tional, income or SES level, there was a fair proportion of medium -high SES levels among them, particularly the younger Negroes. The contrast between the young and the old is noteworthy among Negroes particularly in terms of education and SES level.
