While Ghana was under colonial rule, it was known as the Gold Coast. This was a colony run by people who rarely had the knowledge to run it. The records start in 1846, but Ghana didn't have a trained statistician until 1949. These statistics tell the history of Ghana through its population data, accounts and lists of the colony's officers. Details of its trading partners and social services are also in these records. The books each have a contents page at the front so that you can see if the data set you need is in that Blue Book.
