Within County Movement 



There is undoubtedly much movement within counties but no attempt 

 has been made to measure such movement in this study. The U. S. Census 

 measures the annual mobility status in the Northeast Region as of April, 

 1955, at 13.9 percent of the total population. Of this number 9.6 percent 

 moved in the same county, 2.8 percent between counties, and 1.6 percent 

 between states." The proportionate New Hampshire migration between 

 counties is similar to the Northeast Region and it may be assumed that the 

 proportion of within county movement is similar. 



The Northeast Region is relatively stable compared with the other re- 

 gions of the United States where 29.6 of the West Region residents lived in a 

 different house from the previous year while only 13.9 percent in the North- 

 east moved to a different house.

Age and Migration 



A comparison of the distribution of population in New Hampshire by 

 age groups between 1940 and 1950 indicates a shift in the age composition 

 despite the low net migration. The most noticeable shifts are increases in 

 the proportion of children to 9 years old and of people 55 years and over. 

 There is a decided decrease in the proportion of people 10 to 24 years of 



age.
