Americans were somewhat less mobile in the year ending in April 1954 than in the previous year, according to the results of a sample survey announced today by Robert W. Burgess, Director, Bureau of the Census, Department of Commerce. In Apil1954, 29 million persons 1 year old and over in the United States were living in a different house from the one lived in a year earlier; in April 1953 the corresponding figure was 31,000,000. The number and proportion of short-distance (same county) movers were below the levels of the previous year. The number of movers within the same county--19 million- was down to the levels that existed prior to the Korean conflict, whereas the proportion of such movers--12.2 percent--was significantly below 13 percent for the first time in the 7-year period 1947 to 1954. The proportion of persons abroad at the beginning of the period continued its rise from the low of April 1951, largely as a result of the return of members of the Armed Forced and their dependents. The total mobility rate for 1953 to 195 was virtually the same as that for 1949 to 1950, another year in which there was some decline in business activity.
