In 2019, the Commission on Revenue Allocation proposed the third revenue sharing formula. In the formula, they emphasised population as the main factor for determining revenue sharing. This caused a heated debate and eventually, Senate voted down the formula because it disadvantaged the arid regions.
National revenue is also shared and disbursed by the Treasury through the Constituency Development Fund. The more constituencies a county has the more resources it is allocated. This is why each region wants to have as many constituencies as possible. The determination of the number of constituencies is done through delimitation of the boundaries.
