The Percentage of Workers Employed in Occupations at High Risk for Occupational Morbidity
Rates of occupational injuries and illness vary greatly by both occupation and industry. This indicator focuses on the proportion of workers in occupations at high risk for injury or illness (morbidity). For this indicator, “high risk” occupations are defined as those private sector occupations in the U.S. that have a two-fold or higher rate of injuries or illnesses involving one or more missed days of work. Since the overall injury rate has shown significant declines over the past decade, the actual rate considered “high risk” is modified every five years.
Two data sources are used to create this indicator: data showing occupations with a two-fold or higher injury and illness rate; and the number of workers employed in those occupations in Minnesota. The number of employees in each occupational category is derived from the Current Population Survey (CPS) conducted by the U.S. Census.
State and national data on rates occupational injuries and illnesses are derived from the annual Survey of Occupational Injuries and Illnesses (SOII) conducted by the Bureau of Labor Statistics (BLS) in collaboration with the states. The survey covers most private-sector industries, but only began including state and local government data in 2008. The survey collects OSHA-mandated injury and illness records each year from a stratified sample of employers. Employers not normally required to maintain injury logs (such as specified low risk industries) may be selected to participate in the SOII and must maintain the OSHA logs for the reporting period. However, SOII does not include small farms, federal employees, self-employed, and household workers. The employers are required to provide information on injury or illness cases that result in one or more lost workdays, restricted work activity, job transfer, loss of consciousness, or require medical treatment (other than first aid). National and state data are available from the BLS web site. In Minnesota, the Department of Labor and Industry (DLI) compiles these cases and reports on an annual basis and the data are presented in great detail in DLI’s annual Minnesota Workplace Safety Report.
Occupations that have at least twice the national rate of total reportable injuries and illnesses are classified as high risk. As the overall injury and illness rate has declined, the threshold rate for defining a high risk occupation (at least twice the overall rate) has also declined. For the time frame shown for this indicator, three different threshold rates were used for defining a high risk occupation. For the time period 2000-2002, an occupation was identified as high risk if the occupation had an injury and illness rate greater than 5 cases per 100 full time employees (representing 23 occupations). For the time period 2003-2007, the high risk rate was defined as 2.6 cases per 100 full time employees (representing 82 occupations). For the period 2008-2009, the high risk rate was defined as 2.3 cases per 100 full time workers (representing 61 occupations).
The percentages of workers in high risk occupations in Minnesota are shown in the graph and table below. High risk occupations for the most recent time period (2008-2009) are also shown in the table below.
Due to coding changes and changing threshold rates over each time period, trend analysis was limited to the five-year period 2003-2007. No change was found in the percentage of Minnesotans employed in high risk occupations.
Percentage of Minnesotans Employed in High Morbidity Risk Occupations*, 2000-2009

Percentage of Minnesotans Employed in High Morbidity Risk Occupations in Minnesota, 2000-2009
| Year | Percentage |
| 2000 | 6.5 |
| 2001 | 6.1 |
| 2002 | 5.3 |
| 2003 | 10.1 |
| 2004 | 9.5 |
| 2005 | 9.0 |
| 2006 | 9.8 |
| 2007 | 9.4 |
| 2008 | 14.5 |
| 2009 | 13.8 |
The rate used in defining a high risk occupation was changed for each of the three time periods (2000–2002, 2003–2007, 2008–2009), so comparisons should not be made between any of three periods.
