	In the late 18th century, the first statistical estimates of Commonwealth population appeared. Aleksander Busching estimated the number of Commonwealth population for 8.5 million; Józef Wybicki in 1777 for 5,391,364; Stanisław Staszic in 1785 for 6 million; and Fryderyk Moszyński in 1789 for 7,354,620. Modern estimates tend to be higher; by 1770, on the eve of the partitions, Commonwealth had a population of about 11m-14m, about 10% of that - Jewish. The nobility constituted about 10%, the burghers, about 7-8%.
