Intellectual

Something that comes with the advances in technology is the advances in education. Cultural  diffusion happens because of education in more ways than one. People move all over the world to attend colleges.

Technology

Technology is the best way for people to communicate with people who are in different places. Technology has also offered many jobs. Without technology, we probably wouldn't have the same global connects as we do now.

Economics

Trading blocks and union were made for economics. Without economically dealing other countries can be detrimental for a nation. We have made common currency and duty free zones to help.

Religion

There are new beliefs that are coming out every day. Religion shows cultural diffusion because religion brings people together. As a country, being able to accept all of these new beliefs are very important in the long run. 

Political

Being able to politically connect to other nations in very important for the well- being of all the nations.  G8 is a group that has all of the leaders of the 8 most developed nations. When they meet, you know it's about international importance. This group was made to show that countries

need to stay connected one way or another.

Social

Due to the fact that there are so many  people in the world, there bound to be a mixup of people. People migrate to different place all of the time for various reasons. The USA is a a melting pot just filled with people from all over the world.
