The native language of most people in Limuru is Kikuyu, with Swahili and English widely spoken.
Limuru serves as the capital of Kiambu West District which was formerly part of Kiambu District. In addition, it is also the name of a parliament constituency.
Most of the area of Limuru is now what was previously known as the “white highlands”, a rich agricultural land just south of the equator. The term “white highlands” derived from the British and other Europeans who realised the productive potential of this area and settled in large numbers with the support of the colonial government, establishing coffee and tea plantations, cereal farms and ranches. Altitude of the town is about 2,500 meters. Limuru has a temperature of 10 – 28 °C (75 °F) year round.
