PULSE individual response file

 PUSLE PUF file 

In the context of Census data, PUF stands for Public Use File¹. A Public Use File (PUF) is a dataset that contains individual responses to survey questions¹. These files are used to create custom tabulations and allow users to delve further into the rich detail collected in surveys like the Household Pulse Survey (HPS)¹.

Each weekly HPS microdata file is released two weeks after the Household Pulse Survey Data Tables¹. Each of these weekly releases includes a Public Use Data File (PUF), a replicate weight data file, and a data dictionary¹.

The PUFs contain individual responses to the survey questions and can be downloaded in various formats like SAS and CSV¹. They provide researchers and the public with access to detailed census data, while still protecting the confidentiality of respondents¹².
