Peter Hurford donations made

This is an online portal with information on donations that were announced publicly (or have been shared with permission) that were of interest to Vipul Naik. The git repository with the code for this portal, as well as all the underlying data, is available on GitHub. All payment amounts are in current United States dollars (USD). The repository of donations is being seeded with an initial collation by Issa Rice (see his commits) but all responsibility for errors and inaccuracies belongs to Vipul Naik. Current data is preliminary and has not been completely vetted and normalized; if sharing a link to this site or any page on this site, please include the caveat that the data is preliminary (if you want to share without including caveats, please check with Vipul Naik). We expect to have completed the first round of development by the end of December 2018. See the about page for more details.

Brief history: Peter Hurford was involved in effective altruism from his college days and started donating a significant share of his income as soon as he started earning. He has used his donations both to donate to established charities in global health and animal welfare, and to provide funds for new, fledgling charities in the domains of global health and effective altruism/movement growth

Brief notes on broad donor philosophy and major focus areas: Focus is a mix of global health and development, animal welfare, and effective altruism/movement growth. For the last of these, Hurford has historically focused on new charities, whereas for the first two, he has generally focused more on somewhat more established charities. Also some small donations to other causes, such as civil liberties and political campaigns, as a "good citizen"

Notes on grant decision logistics: For larger grants, Hurford decides the grant amount based on discussion with the recipient charity, and often posts the amount with a TBD before actually making it. In many cases, he writes blog posts covering his reasons for the grant

Miscellaneous notes: Donations entered on Donations List Website are almost entirely a copy of http://peterhurford.com/other/donations.html with a few differences: $3,215 of donations to "Charity Entrepreneurship" in 2017 and $238 in 2018 are not included on the Donations List Website since these mostly cover contract work. See https://contractwork.vipulnaik.com/payer.php?payer=Peter+Hurford for $2,115 of that and a series of blog posts on mental health by Elizabeth Van Nostrand at http://effective-altruism.com/user/Elizabeth/ for some of the other spending. Similarly, $435 of donations to Charity Entrepreneurship for veg advocacy research on 2014-12-14 are not included. Also, $220 for "Help an EA go to EA Global" on 2017-08-03 is omitted. After accounting for these omissions, consistency of totals against the listed totals by year and by donee at http://peterhurford.com/other/donations.html was last verified on 2017-12-31

Similarity to other donors

The following table uses the Jaccard index and cosine similarity to compare the similarity of donors. We are showing the top 30 donors by the Jaccard index because we show up to 30 donors and show only donors with at least one donee in common.
