II. Market Overviews

Market Overview – St. Louis 17 The workforce in the St. Louis area is well diversified, providing increased stability. The mix of jobs in the region is wide ranging and reflective of the national economy. On a 100-point scale for diversity, St. Louis has scored in the 98 to 99 range for more than a decade. Employment gains during the past five years totaled 87,700 positions and have been sourced to nearly every sector of the economy. Top job growth segments include: professional and business services; education and health services; leisure and hospitality; mining, logging and construction; and manufacturing. Cost of living factors in the St. Louis area rank below the majority of major metro areas within the Midwest region. The overall score ranks below the majority of its nearest metropolitan area counterparts and housing costs are a key component of the equation. The St. Louis job market is operating at essentially full employment. Preliminary estimates from the Bureau of Labor Statistics for the month of October 2017 suggest an unemployment rate of 2.7 percent, which would be the lowest level in decades. Selected Urban Areas (100=National Average) Overall Cost of Living Cost of Housing St. Louis, MO-IL 90.5 71.2 Columbus, OH 89.2 76.1 Cincinnati, OH 92.2 76.7 Louisville, KY 92.2 78.6 Indianapolis, IN 92.5 79.3 Kansas City, MO-KS 91.4 81.9 Cleveland, OH 100.2 84.9 Nashville-Murfreesboro, TN 96.3 89.6 Chicago, IL 123.5 156.1 Source:United States Bureau of Labor Statistics; C2ER.

Market Overview – Kansas City 18 Population within the Kansas City area reached an all-time high during the past year. The community’s resident base expanded by approximately one percent, which outpaced the national average. Overall population reached 2.1 million as the rate of growth accelerated. Employment gains during the past five years totaled 93,500 positions, with white-collar positions contributing more than any other sector. The largest contributors of growth include: professional and business services; education and health services; leisure and hospitality; retail; and manufacturing. Expansion of the overall employment base and relatively tight supply of labor has resulted in rising wages. Average wages in 2017 have increased by an average of 7.4 percent in the 10 months of 2017 within the Kansas City metro area, which was more than double the rate reported for the nation as a whole. Housing construction has escalated as population and employment growth have trended positively. The number of new homes entering the construction phase during the past 12 months reached nearly 10,000, tripling the pace of activity just a few years ago. Housing demand has helped support the construction sector of the economy. National Average 7.4% Average Source:United States Bureau of Labor Statistics; United States Census Bureau.

Market Overview – Cincinnati 19 Employment growth is accelerating in the Cincinnati, Ohio area. On a trailing 12-month average basis, establishment-based employment (those working in Cincinnati businesses) growth is at the highest level in more than a decade at 2.1 percent. Employment gains during the past five years totaled 86,600 positions and have been well diversified. Top job growth segments include: leisure and hospitality; education and health services; financial activities; manufacturing; and professional and business services. The overall cost of living remains relatively affordable in the Cincinnati area, and the housing market provides opportunity for future growth. The cost of living remains below the national average and the community ranks in the top 15 percent of all major metro areas in terms of housing affordability. Incremental demand in the housing market confirms that the area continues to be sought out by residents. The number of new home permits has nearly doubled since 2011. During the past 12 months, the single-family market reported a 17.2 percent increase in permitting activity.
