The Centre on Wealth and Philanthropy at Boston College is undertaking a large-scale survey into the cultural underpinnings of wealth for society. The centre said it is the first large-scale survey to focus exclusively on households with at least $25 million in net worth, with many of the respondents above $100 million. The objective is to study the attitudes, practices and personal philosophies of ultra high net worth households in respect of wealth and philanthropy. The research is being funded by grants received from the Bill & Melinda Gates Foundation and Calibre, a division of Wachovia Wealth Management.
