The Central and Western Provinces later became the Western Region after Onitsha had been detached and merged with the Eastern Region, and Idah and its environs merged with the Northern Region. The Central and Western Provinces now constitute the Western and Midwestern Regions. The figure of 1.58 m. for Western and Midwestern Nigeria in 1901 in Table 1 is 1.62 m., less the population of Onitsha and Idah.

In 1911 the population figures for Southern Nigeria were given for the Western, Central, and Eastern Provinces. Parts of the present Eastern and Northern Regions were included in the Central Provinces (now the Midwest), so the figures have been adjusted accordingly.

^{Page 386 note 2} Figures quoted for almost all African countries bear little or no relation to reality, as most of them are estimates. For instance, in French-speaking Africa no complete censuses were held in colonial times, and even now population figures are based on sample surveys. In other areas where censuses have been held, reliability is no higher than in Nigeria.
