I'm not sure I can adequately relate to the term "require." I've witnessed enough poverty (both in the US and abroad) that I have a hard time justifying a requirement for more than

1. clean drinking water, and sufficient food to meet my nutritional requirements
2. sufficient space to successfully obtain a full-night's sleep
3. comfortable temperature, possibly accomplished through bedding or at least a decent climate
4. clean sanitary facilities (latrine, bathing)
5. some method for keeping the insects and reptiles away while I sleep.

This would probably leave me in better accommodations than a large percentage of the world population. Having said that, if we're talking about the amount required to be satisfied, I'd probably bump those requirements up slightly and add
 
6. a source of positive social interaction, and
7. high-speed internet access

to the list.
