This side of the form has some really valuable information.
The National Archives has a page to define what is published in the 1950 Data set.
The 1950 Census dataset - over 165 terabytes of data - includes the metadata index, the population schedule and other forms, the enumeration district maps, and the enumeration district descriptions for the 1950 Census records. Technical details for each part of the dataset are provided below. The 1950 Census dataset was digitized by the National Archives and Records Administration (NARA) and released publicly on April 1, 2022. The AWS Registry of Open Data , started in 2008, is a service provided by AWS to store open, public datasets for free so that they can be accessed and analyzed on AWS.
The 1950 Census population schedules were created by the Bureau of the Census in an attempt to enumerate every person living in the United States on April 1, 1950, although some persons were missed. The vast majority of forms in the population schedules are standard large form population schedules, which list up to 30 names with corresponding responses to the census questions collected by census enumerators. The reverse side of the P1 form asked questions concerning the characteristics of the inhabitants' housing. The housing (reverse) side was not microfilmed (in 1952) at the same time as the population (front) side of the form, so they are no longer extant. Only the aggregate statistical housing data remains preserved in the published reports of the Bureau of the Census. Scattered throughout the population schedules, there are Individual Census Reports and other forms that were used for special circumstances. In other circumstances, information from individual reports were transcribed into the standard schedule forms.
Approximately 6.5 million digital TIFF images and corresponding JPEG derivative images of the microfilmed P1 “1950 Census of Population and Housing” forms and a scattering of Individual Census Reports and other forms for U.S. states and territories.
