UPDATE: Complete data is now available here.
The collected data included about 50 of the top programming languages in regular use. The popularity value is how a given language compares against all other languages. The employment number is an estimate for all of the US. The salary number is averaged over all the US. Please note this data is only an estimate.
Below are two tables showing the top 10 languages organized by popularity/employment and by salary. Interestingly, there is no overlap between the two. Maybe it is due to supply/demand or maybe just error in the data.
