Twenty-eight million persons, or about 1 out of every 5, in April, 1949, were living in a different house from the one they had lived in a year earlier, according to the results of a sample survey announced today by Roy. V. Peel, Director, Bureau of the Census, Department of Commerce. Of the 28 million, 19 million had moved within a county, 4 million had changed county of residence within a State, another 4 million had moved from one State to another, and half a million had been living abroad a year earlier. There is some evidence of a sligh decline in migration between April, 1948, and April, 1949, as compared either with that between April, 1947, and April, 1948, or between August, 1945, and August, 1946 (the year following V-J Day)
