The city's largest employment sector is agriculture, fishing and forestry, representing 24 per cent of the workforce. Farmland comprised over 60 per cent of the land within the city's boundaries in 2012, mostly in the outer areas surrounding the urban core. As is the case nationwide, much of the agriculture in Kigali is subsistence farming on small plots, but there are some larger modern farms close to the city, particularly in Gasabo district, which has the highest average area of cultivated land per household in the country. Other major employment areas in the city are government, which comprises 12 per cent of the workforce, transportation and communication, construction, and manufacturing. The NISR classifies 21 per cent of the workforce as being employed in "other services" such as utilities and financial services, the latter including banking, pensions, insurance, microfinance, and the Rwanda Stock Exchange, which launched in 2011.
