Is there an American city with a higher number of non-governmental organizations (NGOs) per capita than Washington, D.C.? I doubt it. Some people call them private voluntary organizations or PVOs. Maybe there is a difference between an NGO and a PVO, you tell me. Sometimes these institutions are fully funded by a government. Sometimes they are funded by a number of governments. Sometimes they receive no government money at all. In many cases, they receive money from a combination of sources. For example, private universities are NGOs. Some NGOs are called five-o-one-see-threes — 501 (c) 3s — meaning they serve noble causes and if you give them money, you can write your donation off your taxable income, if you have any. 501 (c) 3s are above greed; they are also known as "not-for-profits."
There are plenty Poland-related NGOs in the Washington metropolitan area. This list will
never be complete. These are just examples. When you click on the links below, search
for Poland.
