 The period between 1960 and 1970 saw rapid industrialisation and expansion in Accra's manufacturing and commercial sectors.This contributed to high rural-urban migration to the city, and consequently a high population growth rate.The stagnation of the Ghanaian economy during the 1970s slowed the growth of Accra's population, as shown by the falling growth rate of the 1970–1984 intercensal years.
