This report presents statistics for the United States and selected standard metropolitan statistical areas (SMSA's) on the social and economic characteristics of immigrants and their children for selected countries of origin. The statistics are based on the 1970 Census of Population.
The text consists of an introduction and Appendices A through E, which appear after the tables.
Content of the Tables
Sample size. The statistics in this report are based in part on the 15-percent sample and in part on the 5-percent sample adjusted to represent the total population (see "Data Collection Procedures" in Appendix A). An explanation of the ratio estimation procedure and information on the sampling variability associated with the data are contained in Appendix D.
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.
