I am looking to obtain count of population by census tract. The ideal output would be Census Tract 1919.01 Population = 7,435.
Does anyone know of resources where I can get this information. I tried searching Census.Gov w/ no luck.
You might find the TIGER page helpful in finding information. For instance, this shapefile purports to contain basic demographic information by 2010 Census Tract. There are other types of information you might find interesting as well.
If you want to find your own Census Tracts, you can use this user interface, known as the American FactFinder to find your area of interest.

In one download you'd have the Tract ID numbers, the 2010 Population, and the population centroid in Long / Lat (NAD 83) for each feature:
