Chapter 2. Age and Sex Structure2000 FSM Census of Chuuk State1994 structure and 2000, where the length of the bars at ages 0-4 and 5-9 narrowed considerably compared to the barsfor the same ages for 1973 to 1989 structures.Table 2.3 shows the distribution of the Chuuk population by five-year age group and sex for 1994 and 2000 Censuses.The distribution showed that the older the age group, the smaller the proportion. This pattern was true for both 1994and 2000. For instance, in 2000 14 percent of the population were below 5 years and 1.2 percent were aged 75 andabove. This decline with age reflects the effect of mortality and some migration. A similar pattern is also foundbetween the sexes, though at different levels.Table 2.3: Population by Age Group and Sex, Chuuk State: 1994 and 20001994 2000Number Percent Number PercentAge groups Total Males Females Total Males Females Total Males Females Total Males FemalesTotal 53,319 27,299 26,020 100.0 100.0 100.0 53,595 27,158 26,437 100.0 100.0 100.0Less than 5 yrs 8,440 4,388 4,052 15.8 16.1 15.6 7,347 3,742 3,605 13.7 13.8 13.65 to 9 years 8,100 4,269 3,831 15.2 15.6 14.7 7,305 3,735 3,570 13.6 13.8 13.510 to 14 years 7,711 3,955 3,756 14.5 14.5 14.4 7,356 3,899 3,457 13.7 14.4 13.115 to 19 years 6,063 3,208 2,855 11.4 11.8 11.0 6,772 3,429 3,343 12.6 12.6 12.620 to 24 years 4,452 2,238 2,214 8.3 8.2 8.5 4,836 2,566 2,270 9.0 9.4 8.625 to 29 years 3,471 1,763 1,708 6.5 6.5 6.6 3,998 1,966 2,032 7.5 7.2 7.730 to 34 years 3,171 1,566 1,605 5.9 5.7 6.2 3,151 1,580 1,571 5.9 5.8 5.935 to 39 years 2,858 1,432 1,426 5.4 5.2 5.5 2,847 1,396 1,451 5.3 5.1 5.540 to 44 years 2,454 1,257 1,197 4.6 4.6 4.6 2,571 1,278 1,293 4.8 4.7 4.945 to 49 years 1,764 917 847 3.3 3.4 3.3 2,225 1,124 1,101 4.2 4.1 4.250 to 54 years 990 495 495 1.9 1.8 1.9 1,560 769 791 2.9 2.8 3.055 to 59 years 1,028 495 533 1.9 1.8 2.0 851 407 444 1.6 1.5 1.760 to 64 years 943 495 448 1.8 1.8 1.7 831 392 439 1.6 1.4 1.765 to 69 years 701 319 382 1.3 1.2 1.5 720 336 384 1.3 1.2 1.570 to 74 years 611 280 331 1.1 1.0 1.3 478 217 261 0.9 0.8 1.075 yrs & over 562 222 340 1.1 0.8 1.3 747 322 425 1.4 1.2 1.6Source: 1994 FSM Census, Table P13; 2000 FSM Census, Table P2-1.Median AgeThe median age is a measure that divides the population into two equal parts (the age at which half of the population isolder and half is younger). Change in the median age shows if the population is aging or growing younger. Themedian age is especially useful as one measurement when comparing the composition of a population over time and toother populations.The median age increased by about two years in the 27 years before the 2000 Census, indicating that the Chuukpopulation is aging (Table 2.4). From 1973 to 2000 the median age for both males and females increased by two years.The median age varied geographically in Chuuk in the last census, as well as the census years before that. Over thethree decades observed, the Lagoon median age increased by 1 years while the median age for the outer islandsincreased by 4 years. This shows that the Outer Island population had aged. The median ages for both the Lagoon andthe Outer Islands in 2000 was about 19 years.Table 2.4: Median Age by Municipality and Sex, Chuuk State: 1973 to 2000Total Males FemalesRegion1973 1980 1989 1994 2000 1973 1980 1989 1994 2000 1973 1980 1989 1994 2000Total 16.5 16.7 15.8 17.0 18.5 16.1 16.1 15.1 16.6 18.2 17.0 17.2 16.7 17.4 18.9Lagoon 16.9 16.5 16.0 16.9 18.3 16.8 16.0 15.4 16.6 18.0 17.2 17.0 16.7 17.2 18.7N.

In 1973 the regions in the Outer Islands had a feminine population whereasregions in the Lagoon had rather masculine ones. However, in 2000 both areas display a rather masculine population.22 Chuuk Branch Statistics Office, Division of Statistics, FSM Department of Economic Affairs
