Historical Population Database of Transylvania

HPDT is a historical population database covering, mostly, the second half of 19th Century. The database was built with the financial support of EEA Grants&Norway Grants by Centre for Population Studies (https://csp.centre.ubbcluj.ro/).
The bulk of sources is formed by parish registers of various denomination. The database covers around 10% of the total population of Transylvania at the time (5.4 million births), extracted from 12 micro-zones, scattered across Transylvania.
