Last time I looked, the images are only available at a Family History Center, most of which are still closed.

The 1848 Hungarian Jewish Census (The Census) was known by its Latin name, "Conscriptio Judaerum. 1848".  It is a survey of Jews in Hungary compiled after the failed Hungarian 1848 Revolution against Austria in the Spring of that year.  Though most of it was completed in 1848, in some counties (megye) it spilled over into 1849.  Most of the counties followed the same pattern and were supposed to collect the same data.  However, as no forms were supplied the data was collected in some cases on printed forms, but in most cases on plain paper with each recorder following his own locally created hand drawn form or pattern.

The “Census” covered all the counties of Greater Hungary as we refer to the territories under the Hungarian Crown prior to 1918, which included, among others, parts of Slovakia, Croatia, Ukraine and Romania.

Unfortunately, we do not have access to the entire Census.  The main available source at the present time consists of data that was made available to the Church of Jesus Christ of Latter-day Saints (LDS), and was microfilmed in 1970, on seven microfilms.  These microfilms are listed in the Family History Catalog (FHLC) of the LDS.  They may be found by Subject ("Jews - Hungary") then ("Conscriptio Judaerum"), by Author ("Magyarország. Belügyminisztérium") then ("Conscriptio Judaerum").
