I am trying to explain a graph and if you see any mistakes, please correct me.

The graph shows the number of immigrants from different continents( such as Africa , Asia and Europe)who moved to USA between 1987 and 2002 . It also give a projectiong for 2010.( I am trying to say based on the figure, we can predict the change of immigrants number in 2010)
It also gives a projection for 2010.

You might also want to consider: prediction, expectation
Thanks for your reply. Do you see any other mistakes? Please let me know.

And make sure that the spacing in your final draft is consistent.
