The Iowa Leading Indicators Index increased 0.1 percent, but due to rounding, state Department of Revenue officials say it remained at 107.5 in January 2014. The change was slightly weaker than the previous three months, according to the agency’s report. The monthly diffusion index remained at 62.5, with five of the eight components experiencing positive changes for the second consecutive month. Employment growth continued in January for the 40th consecutive month with the 0.11 percent monthly growth considered relatively strong by department analysts. The index’s recent moves suggest that Iowa employment growth will continue well into spring, officials said. The two most positive contributors in January were diesel fuel consumption and average weekly manufacturing hours. Other positive contributors were the Iowa stock market, average weekly unemployment claims (inverted), and residential building permits. There were three negative contributors in January -- the yield spread, the new orders index, and the agricultural futures profits index.
