To get an idea of the size and the composition of the population resident in the D.I. Jogjakarta we depend chiefly on the extensive data collected in the last census taken in 1930.
Although, therefore, these data are no longer recent, they are still of importance because of a lack of later data of a comparable extensiveness and a same degree of reliability.
However, when recent data are available, we shall mention them for purposes of comparison.
The 1930 census taken in the whole of Indonesia relates to the factual population present in a particular district in the night from 7 to 8 October 1930.
In the D.I. Jogjakarta district 1,559,027 people were counted at the time. The administrative division of 1930 in this area being different from the present on, the numbers have been converted to suit the present division so as to make them comparable to the more recent numbers. This conversion was possible because many figures were mentioned ketjamatan-wise.
Where the province of Central-Java is described it should be under-stood to include the area of the former princedom of surakarta.
The one and a half million people counted in this district in 1930 appeared to be divided over the four kabupatens and the city of Jogjakarta in the following way: See the next page, table II-1.
The reliability of these figures is great because in the areas out-side the town people were counted by counters, who were fully aware of the circumstances of those counted, so that the data supplied could be checked. This circumstance did not prevail in the town to the same extent as it did in the country.
On verifying part of the figures relating to the town it appeared that these were very trustworthy, too. The data of 1955, so 25 years later, come from the administrative census furnished by the lurah desa to the central office of population registration in Jogjakarta. These are less reliable because of the registration of both births and deaths being probably quite deficient.
A comparison with the former figures re. The number of inhabitants of Jogjakarta shows a rapid increase of this number: a more than fourfold increase in 60 years’ time. Not until after the turn of the century did the town clearly start growing.
Table II – 2.
Number of inhabitants of the town Jogjakarta since 1885
As an illustration of the fact that the inhabitants of the town increased in number more rapidly than those of the rural areas, the figures denoting this ratio have been placed side by side in Table II – 2.
The rapid growth of the town appearing from these figures was ascertained in other towns in Java, too, after 1920.
Urbanization was strongest in Java in towns of more than 100,000 in habitants. The smaller towns increased their population at a slower rate.
The city of Jogjakarta is the third largest in Central-Java after Semarang of 378,000 inhabitants and Surakarta of 372,800 inhabitants according to the statements of 1955.
