The Baja California population will grow at rate of 2.40% annually, from 2.8 million in 2005 to 4.5 million inhabitants in 2025, which is consistent with the projections reported by the CONAPO (2005) (National Population Council). The growth trend for the number of customers in the residential sector is less than the growth rate of housing, causing a decrease in the number of people per home and per customer.
