Dwelling Units in United States Cities, 1940 Source: United States Bureau of the Census FAMILIES (DWELLING UNITS) IN LARGE CITIES, JAN. 1, 1939 Housing by States, 1940 Source: United States Bureau of the Census AVERAGE SIZE OF FAMILY FOR THE UNITED STATES, BY STATES: 1940 The decline in average size of family since 1890 tion Censuses of 1940 and 1930. can be attributed largely to the decline in the birth rate and to the setting up of separate households of two or more families previously living as one unit. The more rapid decline since 1930 reflects, no doubt, the adverse economic conditions prevailing during the greater part of the decade. The figures presented here are based on the number of occupied dwelling units from the Housing Census of 1940, and the total population and the number of private families from the Popula-between 1930 and 1940. If there had been no change in the average size of family from 1930 to 1940, the percent of increase in number of families would, obviously, have been the same as that in population. Instead of the increase of 4,956,962 families which occurred during the past decade, the increase would have amounted to only about 2,150,000 families. The decline in size of family may thus be said to account for more than one-half of the gain in the number of families Average Population Per Occupied Dwelling Unit in 1940 and Average Population (Revised figures for occupied dwelling units; final figures for population) Average population per occupied dwelling unit 1940-per private family 1930 Division and 1 These percentages are based on the computed average population figures before rounding to tenths. Urban Places in the U. S. with Population Exceeding 2,500 Source: United States Bureau of the Census Urban areas, as defined by the Census Bureau, include all cities and other incorporated places having 2,500 inhabitants or over. This was extended in the 1930 Census so as to include townsihps and other political subdivisions (not incorporated as municipalities) which had a total population of 10,000 or more and a population density of 1,000 or more per square mile. In New Hampshire and Rhode Island, towns (townships) are classified as urban if they have more than 2,500 inhabitants and certain urban characteristics, and a few large townships in other states are likewise classified as urban under a special rule and are indicated by the letter "T." Towns that are not listed as urban under special ruling by the Bureau of the Census are not included. ARKANSAS-Continued ALABAMA CALIFORNIA-Continued |
