Bulgarian population increased from two million at the 1881 census to two and a half million by 1892, and stood at three and a half million by 1910 and at four million by 1920. This increase took place while a large number of Bulgaria's Turkish-speaking inhabitants were emigrating. At the census in 1881 the Turkish-speaking people in Bulgaria and Eastern Rumelia were about 700,000 and represented 24.9% of the population, yet by the 1892 census the proportion was 17.21 percent and by the 1910 census 11.63%; in the same years the Bulgarian speaking people were 67.84%, 75.67% and 81.63% of the total.
