HEREDITy AND SELECTION IN SOCIOLOGY 



further be remarked that M. Bertillon has omitted several dis- 

 tricts, such as Norwood, Streatham, Dulwich, Blackheath, and 

 Highgate, which are all of them wealthy districts, or at aU events 

 very well off. However, this omission does not in any way 

 affect the value of the results set forth in the above table, which 

 may be summarised as follows : 



Thus, in London, as in Paris, the wealth of a district is in 

 inverse ratio to its birth-rate, the latter diminishing steadily as 

 the former increases. 



The same results are obtained in Berlin and Vienna. Berlin 

 is divided into sixteen different Standesamter, which M. BertiUon 

 has classed as he has classed the twenty arrondissements of Paris, 

 according to their degree of opulence or poverty. The following 

 are the net results obtained : 



Very Poor, 

 (2) 157 



Poor. 



(3) 129 



WeU-off. 

 (4) 114 



Very Well-off. 

 (3) 96 



Rich. 



(3) 63 



Very Rich. 



(1) 47 



The figures in brackets show the number of Standesamter in- 

 cluded in each category ; the other figures show the average annual 

 number of births for 1,000 women from fifteen to fifty years of 

 age during the period 1886-94. Here, again, we find steady and 

 regular diminution of the birth-rate according as the material 

 prosperity of the Standesamter increases. 



In Vienna the same phenomena are seen. Vienna is divided 

 into nineteen Bezirfce, and, stiU following the classification adopted 

 by M. Bertillon, we get the following result as regards the birth- 

 rate of each category : 



Very Poor. 

 (4) 200 



Poor. 



(4) 164 



Well-off. 

 (3) 155 



Very Well-off. 

 (2) 153 



Rich. 

 (5) 107 



Very Eich. 



(1) 71
