The Wage section tells you how much money most workers in an occupation earn at the state level. Annual wage data appear for most occupations. The annual wage is based on working full time, 12 months of the year.

The wage graph provides two types of information about wages - the median wage and the wage range.

The median wage is represented by the vertical line inside the shaded bar. Half of all workers in the occupation earn an amount below the median wage and half of workers earn an amount above the median wage. Move your cursor over the bar to see the median wage value.

The wage range is represented by the shaded bar, a range that half of all workers in the occupation earn. 25% earn less than the low amount and 25% earn more than the high amount. Move your cursor over the bar to see the wage range values.

If the graph does not display a median wage it is because it is representing several occupations. In this case, the median wage range displays in the wage statement.

For more information see the Wages topic.

In Illinois, detectives and investigators earn a median wage of $82,905 per year.

Employment and Outlook 

Employment and Outlook

The Employment and Outlook section gives you information about the size of an occupation, whether it is growing or declining in size, and how many job openings there may be each year.

There are five size categories for occupations in CIS: very small, small, medium, large, and very large. Similarly, five categories are used for the number of job openings: very few, few, moderate, high, and very high.

Five categories are also used for growth: declining, more slowly than average, average, faster than average, and much faster than average. The growth rate tells you how rapidly an occupation is expected to grow in comparison to all other occupations. This information is an estimate. No one can predict exactly how many jobs will be available. The rate of growth of an occupation is determined by several factors. A few major factors are the state of the economy, competition, technological advances, and environmental rules.

For more information see the Employment and Outlook topic.

In Illinois, 2,676 detectives and investigators work in this medium occupation.
