NEARLY ALL OKLAHOMA COUNTIES HAVE DECLINING UNEMPLOYMENT RATES THE PAST YEAR. There are a number of ways to gauge the underlying strength of a state economy. One useful way is to measure the cumulative health of the individual counties. We often do this using a simple form of diffusion index which is simply the sum of counties with a declining unemployment rate the past 12 months. For Oklahoma the indicator has returned to very positive territory. After sluggishness in the state economy in 2013, the state has bounced back in 2014 with the jobless rate in a distinct downtrend in nearly every county.
