History
Ruiru's population rose from 238,858 in 2009, to 490,120(Kenya census 2019). The rapid population growth being a response to the shortage of available housing in Nairobi. Another factor being the infrastructure development especially Thika Road and Nairobi Eastern Bypass Highway. The town has struggled to adapt to the influx of people. Ruiru is also an industrial town with several major factories, including Devki Steel Mills, Super Foam, Spinners & Spinners Garment Factory and Ruiru Feeds. It is well served by banks and shopping malls and currently is enjoying a housing boom, as many coffee estates are converted into residential areas, including an upcoming multi-billion Tatu Estate. ICT businesses are also emerging, including , a digital village by the KICT board where the community can buy computers and get free computer training.

This area was a sisal and coffee growing district with sisal on either side of the river to the right of the main road to Thika. As can be seen it is now a housing area. There used to be four main manager houses on the estate on the South side of the river. The area was given over to an African consortium to be developed into small holdings in the 1970s.
