less than 20 thousand inhabitants. In 1920, 46.3% of the medical doctors, 41.2% of the veterinarians, 21.4% of the pharmacists of Hungary were Jewish, as well as 34.3% of the journalists, 24.5% of performers of music, 22.7% of the theater actors, 16.8% of the painters and sculptors. Among the owners of land of more than 1000 hold, i.e. 570 hectares, 19.6% were Jewish. Among the 2739 factories in Hungary, 40.5% had a Jewish owner. The following table shows the number of people who declared to be Israelite (Jewish) at the censuses inside the post-WWI territory of Hungary. Between 1920 and 1945, it was illegal for Hungarians to fail to declare their religion A person's religion was written on their birth certificate, marriage license (except in 1919, during the short-lived Commune, see Hungarian Soviet Republic), and even on a child's school grade reports. The net loss for Judaism due to official conversions was 26,652 people between 1919 and 1938, while 4,288 people converted into the faith, 30,940 left it. The endpoints of this period, 1919–1920 (white terror) and 1938 (anti-Jewish law) contributed to more than half of this loss; between 1921 and 1930, the net loss rested around pre-war levels (260 people/year).: In 1926, the districts I, II, III of Buda were Jewish 8%,11%,10% respectively. The 19,000 Jews of Buda constituted about 9.3% of both the total population of Buda and the entire Jewish population of Budapest.

Districts V (31%), VI (28%), VII (36%), VIII (22%), IX (13%) had large Jewish populations, while district X had 6%. The four Neolog communities of Budapest (I-II, III, IV-IX, X) had a total of 66,300 members paying their dues, while the Orthodox community had about 7,000 members paying religious taxes. In the countryside of the post-WWI Hungary, the Orthodox had a slight edge (about 49%) over the Neolog (46%). Budapest and countryside combined, 65.72% of the 444,567 Jews belonged to Neolog communities, 5.03% to status quo ante, while 29.25% were Orthodox in 1930. The Jewish communities suffered a 5.6% decline in the 1910–1930 period, on the territory of the "small" Hungary, due to emigration and conversion.
