Key workers are defined as belonging to the following sectors: agriculture, forestry, and fishing; mining and quarrying; manufacturing; electricity, gas, steam, and air conditioning supply; water supply, sewerage, waste management and remediation activities; wholesale and retail trade, repair of motorcycles and motor vehicles; transportation and storage; information and communication; financial and insurance activities; professional, scientific, and technical activities; administrative and support service activities; public administration, defense, and compulsory social security; and human health and social work activities.
Key workers are largely employed in the private sector, with only 14.6 percent holding public sector employment on average. However, the rate of public sector employment differs greatly depending on the country income group. Fewer people are employed in the public sector in low and lower-middle income countries, given smaller tax revenues as a proportion of the national income and the significance of agricultural employment.
