I need a breakdown of the most popular charities for corporations to
give to. I'm not interested in political donations, which are
motivated by a desire to get favors from politicians. I care more
about where companies give their money when they're trying to "give
back to the community" or give to the needy.

For instance, using some fake data, a sample answer might be:
25% local food drives
20% local libraries
15% boy scouts
15% United Way
15% msc. food aid for Africa
10% Red Cross

If you can't find enough data to give exact percentages, it would also
be acceptable to list the top 10 or so charitable causes or
organizations to which corporations donate.
