Question: Contribution to UN Peacekeeping

I would like to know who the top 50 contributors to UN peacekeeping operations are in dollars as well as troop numbers for each of the last 20 years. Alternatively, one could compile the contributions based on 5 year segments such as: 1980-85, 1985-90, 1990-95, 1995-2000, 2000-05. I would also like to know the total peacekeeping budget for each year.
