The world total in 2011:
The somewhat outdated graph below, showing applications in 36 industrialized countries (OECD), points to a longterm upward trend:

During the most recent years, however, a new increase:
In general, the number of asylum seekers varies a lot over time, depending on the number and severity of crisis situations around the world, on the approval and entry policies of the receiving countries etc.

Most people come from war-torn countries, understandably (Afghanistan, Iraq etc.).
Here are a couple of maps, but I was unable to determine the reference year:
