In 1872, when there were only 10 congregations in the Boer Republic and seven in the Colony, Burgersdorp had a membership of 989, compared to Reddersburg in the Orange Free State's 714.
In the course of 1872, the other congregation in the Colony which was destined to play a major role thanks to its involvement in Reformed and Christian national education, Steynsburg, was separated from Burgersdorp.
[3] Twenty years later, in the Almanac of 1892, Burgersdorp had 1,769 people and 777 members (first in the Colony) and Steynsburg 840 and 417 (third after Middelburg).
In the course of the 20th century, the urbanization of members reduced Burgersdorp's soul count to 729 in 1931 and its membership to 460, and in 1960 to 686 and 481 respectively.
In the meantime, a university, the PU for CHO, developed from the Theological School in Potchefstroom and over time this town became one of the largest Reformed centres.
