HOW THE LIST IS COMPUTED

• Thousands of nonprofit organizations are reviewed in a preliminary screening to determine if their statistics are competitive enough to be ranked.
• 500 organizations are then selected to be ranked.
• Data is collected for each nonprofit for Facebook Likes and Twitter Followers.
• For each of the 6 measured criteria, each organization is ranked in comparison to all other nonprofit organizations being evaluated.
• A composite rank for each nonprofit is determined by giving by 50% weight to Facebook Likes and 50% to Twitter Followers
• The top 50 organizations are published.
