Changes in Missouri Population Age 40 to 64 and Age 65 to 74, 2000-2004
Changes in Missouri Population Age 40 to 64, 2000-2004
People in the population cohort age 40-64 in 2004 are often referred to as the “baby boom” generation. They were born during the period between the end of World War II and the middle 1960s. Following the end of WW II families were reuniting, civilian employment and incomes were expanding, the national birth rate was high and suburbs of the cities were expanding to accommodate the population and economic growth. It was called the baby boom generation because the birthrate during those decades was literally booming.
The babies born during that era are now in the age range between their early 40s and early 60s. This baby boom generation has become the largest population cohort in Missouri and across the nation. Because of the large size of the 40-64 age cohort, there is growing public interest in the baby boom generation and where that population is located. During the next few years increasing numbers of the baby boom generation will become eligible for Social Security and Medicare benefits.

As shown in Table 1 Missourians between age 40 and 64 accounted for nearly one-third (32.6 percent) of the state’s total population in 2004. Map 1 shows there were 44 counties in which more than 33 percent of county population was in the 40-64 age cohort. This population cohort is also rather uniformly distributed throughout the state. Map 1 also shows there were no Missouri counties in which less than 25 percent of total county population was in the 40-64 age cohort.
Map 2, however, shows that in only three counties did the 40-64 age cohort fail to increase from 2000-2004. In 81 counties the 40-64 cohort increased by more than 5.0 percent. That is significant since the total population of Missouri increased by only 2.8 percent from 2000-2004. There were 26 counties in which the baby boom population increased by more than 10 percent. As also shown in Map 2, most of the counties gaining more than 10 percent are in three clusters. The largest cluster is 10 counties surrounding St. Louis City and County, followed by a cluster of nine counties surrounding Kansas City. A smaller cluster of four counties is located in Central Missouri. However, the largest category of counties is the 55 counties whose age 40-64 population increased by from 5.0 to 9.9 percent from 2000 to 2004. Those counties are rather uniformly distributed throughout the state.

OSEDA Regional Grouping of Counties Many demographic factors vary by region within the state of Missouri. For the convenience of our user community, OSEDA prepares tables using three different regional groupings of counties: Extension, Economic Development and Transportation. For each of these groupings, one table summarizes the indicators by regional total and a second table shows values for each county grouped by region. Users may select the county grouping most helpful for their application and understanding. |
Change in 40-64 Population Age Cohort from 2000-2004 by Regions
University of Missouri Extension Regions
Table 2 shows there is virtually no difference in the proportion of 40-64 age cohort population among the eight UM Extension Regions. The proportion for each region was within one percentage point of the statewide proportion. There was, however, some variation in change in the 40-64 population from 2000-2004. The greatest percentage gains were in the East Central Region (12.5 percent) and the West Central Region (12.2 percent). The Central and Southwest Regions had gains of 9.2 and 9.7 percent respectively. Gains in the other four regions ranged from 5.8 to 7.5 percent.
Missouri Department of Economic Development (DED) Regions
Table 3 shows virtually no difference in the proportion of 40-64 age cohort population among the 13 DED Regions. There was, however, some difference among the regions in the percent change of the 40-64 age population between 2000 and 2004. The St. Louis MSA had an increase of 12.6 percent and the Kansas City MSA was virtually the same with an increase of 12.5 percent. There were three other regions that had an increase of near the statewide increase of 10.6 percent. Those regions and the percent change were Springfield - Branson (10.6 percent), Central (10.3 percent) and Lower East Central-Cape Girardeau (9.4 percent). The remaining eight regions had changes varying from a low of 4.0 percent to a high of 8.6 percent.
Missouri Department of Transportation (MODOT) Districts
Table 4 shows virtually no difference in proportion of 40-64 age cohort population among the 10 MODOT Districts. There was, however, some difference among the regions in the percent change of the 40-64 age population between 2000 and 2004. The St. Louis and Kansas City districts both had a 12.4 percent increase in that population. The Hannibal District had an increase of 11.1 percent. Following the Hannibal District the Springfield District had an increase of 9.7 percent and the Jefferson City District had an increase of 8.9 percent.
Missouri Regional Planning Commission Areas (RPCs)
Table 5 shows, just like the other regions, virtually no difference in proportion of 40-64 age cohort among the 19 RPC areas. There was, however, some difference among the RPCs in the percent changes of 40-64 age population from 2000-2004. The largest percent increase (18.3 percent) occurred in the Boonslick RPCs. That RPC only has three counties and two of them (Warren and Lincoln) are among the fastest growing counties in the St. Louis Metropolitan Area. After that exceptional increase there were seven RPCs which had an increase of between 9.5 and 12.6 percent. In order of increase those regions were: the Mid-America RPC (12.6 percent increase), East-West Gateway Coordinating Council (12.4 percent increase), and Mid-Missouri RPC (11.3 percent increase). Following those three were Southwest Missouri Council of Governments (10.2 percent increase) and SEMO Regional Planning Commission (10.0 percent increase).
Changes in Missouri Population Age 65-74, 2000-2004
| Map 3 click map for larger version 
|
While the population age 40-64 accounted for 32.6 percent of Missouri’s total population in 2004 the population age 65-74 accounted for only 6.8 percent, as shown on Map 3. Of course, the 40-64 age cohort includes 25 years while the 65-74 includes but 10 years. However, if the population of those two age cohorts is standardized by comparing the population of each 10-year age interval it shows the population age 40-64 has twice population of the 65-74 age cohort in each 10-year age interval.
While the baby boom cohort is relatively larger than other age cohorts, the population of the 65-74 age cohort is relatively small. People in that age range in 2004 were born during the depression of the 1930s and the early years of World War II. That was a period of low birth rate throughout Missouri and the nation.

Table 1 shows the population age 65-74 in 2004 declined by 1,460 (-0.4 percent) from 2000-2004. However, changes in the 65-74 age cohort were not uniformly distributed. Map 4 shows that, while more than half (61) of Missouri counties declined in 65-74 cohort population from 2000-2004, there were 20 counties in which that population age group increased by more than 5.0 percent. The map shows that a majority of the losing counties are rural counties, especially in north Missouri, although the central city counties, Jackson, St. Louis and St. Louis City also had significant losses.
A majority of counties having a gain of greater than 5.0 percent are suburban counties, especially those on the periphery of Kansas City and St. Louis. The counties having the greatest gains were St. Charles (19.9 percent), Jefferson (12.3 percent) and Warren (12.8 percent) in the St. Louis Metro Area and Platte (23.1 percent), Cass (10.9 percent) and Johnson (9.9 percent) in the Kansas City Metro Area. There were also two counties in the Springfield Metro Area having impressive gains in 65-74 population – Christian County with an increase of 15.3 percent and Webster with an increase of 15.4 percent. Generally, the 65-74 age cohort is increasing in size in, and around, population centers having accessible services such as health care.

Change in 65-74 Population Age Cohort from 2000-2004 by Regions
University of Missouri Extension Regions
As shown in Table 2 there is very little difference among the eight Extension Regions in the proportion of total regional population accounted for by the 65-74 age cohort in 2004. In the South Central Region the 65-74 cohort accounted for 8.2 percent of total regional population. At the other extreme, the 65-74 cohort accounted for only 6.2 percent of the total population of the West Central Region.
Changes in the 65-74 cohort population were quite small in all Extension Regions. There were five regions in which the 65-74 population declined from 2000-2004 in five of the Extension Regions with the greatest loss (-1,564) occurring in the East Central Region. There were three regions which had small increases in the 65-74 population with the greatest gain occurring in the Southwest Region (+1,223).
Missouri Department of Economic Development (DED) Regions
As shown in Table 3 there is very little difference among the 13 DED Regions in the proportion of total regional population accounted for by the 65-74 age cohort in 2004. At the top end there were five regions in which the 65-74 cohort accounted for 8.1 percent or more of total regional population. South Central, with 9.2 percent, was the region in which the 65-74 cohort accounted for the highest percentage of total regional population. In each of the remaining eight regions the 65-74 age cohort accounted for between 5.9 and 7.6 percent of total regional population in 2004.
Changes in the 65-74 cohort population were quite small in all DED Regions. There were seven regions in which the 65-74 population increased from 2000-2004, but only one region, Springfield-Branson had an increase of more than 2.3 percent. There were six regions in which the 65-74 population declined from 2000-2004. Among those six regions only two, North Central (-7.7 percent) and Northwest (-6.3 percent) had losses of greater than 3 percent.
Missouri Department of Transportation (MODOT) Districts
Table 4 shows that the Missouri population age 65-74 accounted for 6.8 percent of the states total population in 2004. The table shows that in eight of the ten MODOT Districts the 65-74 population accounted for between 7.0 percent and 7.8 percent of total district population. The table shows, however, that in the Kansas City District the 65-74 cohort accounted for 6.1 of the Kansas City District total District population while in the St. Louis District the 65-74 cohort accounted for but 6.4 percent of District total.
Of the ten MODOT Districts five experienced a decline in 65-74 population from 2000-2004 while five experienced a gain. The greatest numerical loss (-2,069) occurred in the St. Louis Distric while the greatest numerical gain (1,471) occurred in the Springfield Area.
Missouri Regional Planning Commission Areas (RPCs)
Among the 19 Missouri Regional Planning Commission Areas people aged 65-74, as shown in Table 5, accounted for less than 7.0 percent of total area population in seven of the 19 RPCs, and that age group accounted for between 7.0 and 7.9 percent of total area population in an additional seven RPCs. The RPCs in which the 65-74 cohort accounted for the highest percent of total area population are Kaysinger Basin with 10.2 percent, Ozark Foothills with 9.3 percent and South Central Ozarks Council of Governments with 9.2 percent.
Of the 19 RPCs twelve experienced a loss of 65-74 age population between 2000 and 2004. Among those RPCs the greatest percentage losses of 65-74 cohort population occurred in NWMO Regional Council of Governments (-7.0 percent), and in the neighboring Green Hills RPC with a loss of 6.9 percent. The loss was less than 4.0 percent in each of the remaining ten RPCs.
There were only seven RPCs that experienced a gain of 65-74 cohort population between 2000 and 2004. Of those seven by far the largest increase (9.0 percent) occurred in the Boonslick RPC which includes only three counties, two of which, Lincoln and Warren, have been among the most rapidly growing counties in the St. Louis Metro Area.
