What Is An Outdoor Pauper?

I came across the term outdoor pauper today while searching the 1891 English census so I went straight to Google to find out what it meant.

For all things relating to poor relief and workhouses I turn to www.workhouses.org.uk/. The glossary says that indoor relief or an indoor pauper was a resident of a workhouse who was receiving their poor relief in that way. Outdoor relief was given to those who still had somewhere to live but little to no income.

Here is a definition I found via Google Books;

Ageing and Generational Relations over the Life Course by Tamara K Hareven

Has anyone else come across this before? Have you heard a different meaning?
