Whenever there's a natural disaster like Tuesday's earthquake in Haiti, charity and relief organizations mobilize — not just to help, but also to build their own visibility, profile and donor lists. Deciding whom to give money to can be a challenge: as donors, we want our money to do the most good, and also to help in ways or through channels that appeal to our own charitable interests. My favorite resource for choosing charities is charitynavigator.org. Charity Navigator evaluates the financial health and efficiency of over 5,400 of America's largest charities. Their categorical listings and 4-star ratings for the most efficient charities make it easy to quickly sort through charities to find the ones that align with your personal charitable interests and maximize their use of your money to advance those interests. Interestingly, The American Red Cross — the default organization for many americans giving for Haiti earns only 3 stars. For Haiti relief, Charity Navigator lists thirty 4-Star charities — pick one and give what you can. I chose American Jewish World Service.
