POPULATION DISTRIBUTIONS AND TRENDS

The U.S. population as described in the 1970 Census is used as a basis from which the colony properties are derived. The sex ratio is increased by about 10 percent in favor of the males and it is assumed that there is a substantial shifting of the population out of the more dependent ages - from under 20 and over 45 - into the 21-44 age class. Other assumptions include an increase in the participation of married women in the labor force and some fairly serious adjustments in the marital status distribution, all of which are directed toward increasing the proportion of the population in the effective workforce. These data are shown, with some comparable statistics for the United States, in tables 4-9 to 4-13.

From the numbers in table 4-14, it is apparent that systematic differences as to the proportions of the labor force engaged in production for export exist among U.S. communities of varying size. At a minimum, the percentage of workers engaged in work pertaining to the internal functioning of the community is approximately 30 percent, leaving 70 percent for export industry and for those who, by industrial standards, are not considered productive. These approximations are modified slightly to reflect features of early settlement, including a somewhat higher proportion of workers in internal activities. Table 4-15 shows the population development and the percentages of workers engaged in export activities for the first 14 yr following the beginning of construction.
