SUMMARY AND CONCLUSIONS
This study has shown that there are very marked differences between the ratios of children to women in various parts of the country and in different nativity groups.
In cities of over 100,000 these differences range from 234 children per 1,000 native white women in Los Angeles to 1,051 children per 1,000 foreign-born white women in Youngstown, Ohio; in cities of 25,000 to 100,000 the range is from 257 children per 1,000 native white women in Brookline, Mass., to 1,277 children per 1,000 foreign-born white women in Hamtramck, Mich.; and in the rural districts the range is from 436 children per 1,000 native white women in Rhode Island to 1,393 children per 1,000 foreign-born white women in West Virginia. Of course the majority of communities are found well within these extremes, the averages being as follows: In all cities of over 100,000 the ratio is 341 for native white women and 679 for foreign-born white women; in all cities of 25,000 to 100,000, the ratios are 390 and 766, respectively; and in the rural districts 721 and 998.
In these three comparisons we find the two chief differences in ratios to the study of which the larger part of this monograph has been devoted. They are, first, the differences in ratios of children between the native and the foreign-born women, and second, the differences between the cities and the country districts.
One meaning of these differences in ratios has been strikingly set forth by calculations of the stationary populations1 that would arise at death rates of 1920 on the supposition that the ratios in rural groups prevailed in urban groups. (See Chap. VI.) On the supposition that the 8,032,720 native white women 20 to 44 years of age living in cities (places of over 2,500 inhabitants) and having a ratio of 388, had the same ratio of children, that is 721, as the native white women in the rural districts, the city women would have had 2,674,645 more children than they did have and this number of____________________
