Though the rate is still.5 percent lower than it was in August 2016, it's a slight increase from the 4.2 percent recorded in July, the state department of Labor and Workforce Development said.
The number of jobs in the area also hit an all-time high of 191,751, which was up more than 5,100 from a year ago. The national rate has dropped one-half of a percentage point in the same span, the Department of Labor & Industry report said.
Nationally, unemployment was 4.4 percent in August - up one tenth of a percent from July - while the country's labor force and the participation rate held steady at 62.9 percent.
The number of people counted as unemployed fell by almost 4,800 in August compared with a year ago. Alaska again held the worst-state title, with a jobless rate of 7.2 percent. The DWD says Indiana's total private employment stands at 6,700 above the November 2016 peak. Over the year, the state's nonfarm payroll jobs were up 2.2 percent with a net gain of 15,200 jobs.
Employment in professional and business services increased by 5,100.
But the state is adding jobs. Administrative and support services, a subsector that includes employment agencies, saw the biggest rise.
Tulare farms shed 700 jobs month-over-month, while nonfarm industries added 1,000 jobs.
Government reported the largest decline, down 1,500 jobs.
