Charitably inclined Americans make significant donations of money and time to causes they support.

In 2014, they contributed some $358 billion to nonprofit organizations, of which $259 billion came from individual donors.

In 2015, the U.S. ranked second on the latest CAF World Giving Index.

Individual circumstances largely influence whether donors contribute money, time or both, as well as the magnitude of its impact, according to WalletHub’s Charity Calculator.

WalletHub recently examined levels of generosity in the 50 states, analyzing eight metrics, including volunteer rate, the percentage of the population who donated time and money, and the median contribution to charity. Researchers gave each metric a value between 0 (the worst value) and 100 (the best value).

Following are WalletHub’s 10 most charitable and 10 least charitable states.
