Borrowing from an approach that sometimes appears in the finance sections of the popular press, LSGL analysis is a handy and versatile way to compare, portray and classify the patterns of growth across all of Iowa's 99 counties.

Here, we adopt this approach to gauge and compare the real total personal income growth of Iowa's counties over the latest available year (2022) against the backdrop of their growth over the previous decade (2013-2022). In so doing, we classify their growth and performance into 4 broad categories: Leading, Slipping, Gaining and Lagging. Particular attention is given to highlighting and assessing the growth of total personal income.

This LSGL module dynamically generates and calibrates a barometer for gauging the economic growth and performance of the 99 counties of Iowa wherein "...unlike in the land of Lake Wobegon, not all the counties are above average."
