Trans Nzoia County’s arable land makes agriculture the top economic activity, where maize farming is widely practised, and mostly at a commercial level. Tea, coffee, horticulture and commercial businesses are also very significant to the county’s economy. There’s dairy farming and tourism – owing to an array of touring sites within the county. A number of companies such as Kenya seed company, Western Seed Company, K.C.C and various government institutions provide employment to many people living in the urban centers.
