Giving as a percentage of GDP

Last evening there was this panel discussion on NDTV Profit on giving as a corporate culture. The participants, corporate honchos, did not have much to offer but one side view of the voluntary sector. Although, anchor rattled some figures that were interesting enough. He compared charitable giving as a percentage of GDP. According to him US gives 2.5% of its GDP. UK gives 1.75% of its. Amongst BRIC, India gives 0.6% of its GDP while Brazil and China languish at 0.3% and 0.1% respectively.Lots of catching up to do for the formidable BRIC.
