There have been many unusual changes in the census. Pezuela's population had its maximum peak during the 1950–70 period, yet the advent of the new century carried a severe decline in the number of dwellers with it. Nowadays, the village keeps a regular population of over 800 inhabitants. Nonetheless, as previously described, in some festivities the town's population surges as a result of the arrival of people from Madrid and Alcalá de Henares.
