In terms of size, some of
the larger islands were very sparsely populated. . Tinian and Rota, .
for instance, while nearly as Jarge as Saipan, had much smaller popuIntions. On some of the tinyislands with an area of Jess than 1 square
mile, the population density was far greater than on the larger islands.
Population density in terms of over-all area was misleading in numevous instances for. on manyof the larger islands, only a very small area
was inhabitable. This was especially true ou the volcanic islands
where much of the island was too rocky to be inhabited. The result
was a concentration of population in a very smal) area with an extremely high population densitr. while the rest of the island had few
or no inhabitants at all?
Table 1 shows by district the numberof females visibly pregnant at
the time of the health survey. Estimated annual birth rates based on
these figures are alsoshown. For comparative purposes, in the United
States in 1949 birth rates per 1,000 estimated female population, between the ages of 15 to 44, were as follows: all races, 105.2; white,
102.6: and nonwhite, 126.4.
Age distribution. The median age for the three districts combined
was 23.0. Over one third of the population was under 15 years of
