The number of employed Iowans grew again in July, for the 34th month in a row, according to a monthly report of economic indicators compiled by the Iowa Department of Revenue.

The overall index was 106.6, which also has been creeping upward since April.

The economic indicators that improved in July compared with a 12-month average were housing, the stock prices of 33 Iowa companies, manufacturing hours and new orders, and yield spread, which is a measure of the difference in yield between long-term and short-term Treasury securities. Unemployment claims, the price of diesel fuel and agricultural profits declined against the 12-month average.
