and 266 in smaller towns. Among administrative employés the cor­ 
responding numbers were 183, 198, 215, or 92%, 87%, 81% of those 
previously cited. Employés have in a way a specific fertility which depends 
less on their surroundings than that of workmen. 
Analogous results are obtained if one compares the proportion of sterile 
marriages. Among marriages which have lasted for more than 25 years, the number 
of sterile cases per 1,000 increases with increasing yearly income.

To sum up, the statistics of French families, of which a brief account 
has just been given, confirm what has been previously learnt by researches 
as to the influence on fertility of social status, social surroundings, and 
income. Further, they provide better data from which conclusions may 
be drawn as to what occupations are favourable and what unfavourable 
to the birth of children. 
It appears that in France paupers, vagabonds, prisoners, etc., the 
descendants of whom form an undesirable addition to the population, are 
rather lower than the average in productiveness, but among these are 
reckoned many who' are in confinement, whose fecundity is therefore tem­ 
porarily put a stop to. Further, legitimate children only have been dealt 
with. Agriculture, manufacturing industries, commerce, and the learned pro­ 
fessions, which form the backbone of the population, admit in some ways of 
division into specific classes. The least productive families would be those 
of employés and workmen in the public services and domestic servants. 
After them come members of the learned professions, the bank clerks and 
commercial employés, and employés of all classes. Then come commercial 
employers, small manufacturers and those with moderate sized businesses, 
farmers, persons who live in engaged on farms or in industries, large em­ 
ployers of labour, workmen in small and medium-sized industrial concerns, 
and agricultural labourers; then, with a higher degree of productiveness, 
day labourers and manual labourers in towns, fishermen and sailors, and
