KeyError: 'long'"
It appears as though the Census variables resource now reports these types as "long" which isn't in the supported types mapping.
I installed census yesterday and am still having this issue. I have tested with ACS 5 year variables B25064_001E and B25070_001E, ACS1 B25064_001E, ACS5DP DP04_0132E, and ACS1DP DP04_0132E. I have the same problem with SF1 variables.
The package overall has been great and I appreciate the work, but unfortunately right now it is not usable.
Could somebody please help fix this issue or suggest a workaround?
I have the same KeyError: 'long' and I need to do a query for median income.
Thanks a lot.

A fix has been pushed out - If you're using pip, you should be able to install it by doing
pip install --upgrade git+git://github.com/datamade/census@master
