A closer examination of the net migration by age group in Table 4 

 bears out these preliminary observations. There was a net movement into 

 the state of children up to 14 years of age. There was a marked out-migration 

 of those who would have been in the age group 20 to 34 by 1950 for both 

 males and females. The exodus of males is greater than females during this 

 period. The paradoxical situation of an increase in children and a decline 

 in the age groups most likely to have children born in this period can best 

 be explained by assuming that the out-migration of these age groups was 

 mainly from unmarried persons. The couples with children who moved to 

 the state in that period plus the increased birth rate probably accounted 

 for the proportionately large number of children under 10 years of age. 

 There was some decline in the 55 to 64 age groups but all others showed 

 in-migration.

Migration by Age Groups for Each County 



There are differences in net migration among the counties in New 

 Hampshire as shown in Table 1. There are also marked differences among 

 counties in the proportion of each age group which migrated. This is em-
