While basic demographic studies, such as censuses, were conducted in the ancient world as far back as 6,000 years ago, demographers as we know them, such as John Graunt from the United Kingdom, came about in the 16th century.
The Materials of Demography
Censuses, although usually not including all individuals, were carried out in the ancient world in powerful states such as Egypt, Babylon, Persia, India The Analysts

Bulatao, Rodolfo A., and Ronald D. Lee, eds. 1983. Determinants of Fertility in Developing Countries: A Summary of Knowledge The development of the discipline of demography is usually traced to

Made upon the Bills of Mortality (1662) examines the weekly records of deaths and baptisms (the “bills of mortality”) dating back to the end of the 16th century.
The initial population "upswing" began around
