Some of these columns are the same data but named differently between the Facebook CSV ad reports and the Graph Ads API, while the other columns are calculated from the existing columns.

http://developers.facebook.com/docs/reference/ads-api/adstatistics/

Reach is called unique_impressions in the ad_statistics object.
Social_Reach is called social_unique_impressions.
Frequency = impressions / reach
CPC = spent / clicks
CPM = spent*1000 / impressions
