Issue downloading block-level data from the 2010 decennial, summary file sf1

[mleonardos317]

get_decennial is not working for the following parameters:

geography <- "block"
year <- 2010
sumfile <- "sf1"

other values of geography, ie tract, work just fine
other years work, ie 2000, work just fine
the values input for state, variables or any other parameters don't appear to make a difference.

when using get_decennial for block level 2010 sf1 data, the command runs but returns an empty data table.

Thank you for looking into this!

For example, this returns an empty table.

tidycensus::get_decennial(geography="block",
variables="P012003",
year="2010",
sumfile="sf1",
state="50")

And this throws an error:

tidycensus::get_decennial(geography="block",
variables="P012003",
year="2010",
sumfile="sf1",
state="50", county="50001")

Error message:

Unfortunately, the Census API has removed the ability to get block-level data by state in the 2010 Census. We'll need to either iterate over counties or throw an error in the next release.

Regarding your code @cnoelke, you don't need to specify the state code as part of the county code. This works:

tidycensus::get_decennial(geography="block",
  variables="P012003",
  year="2010",
  sumfile="sf1",
  state="50", county="001")

Confirming that state-by-county download is working. Gotta add that extra county loop now. Thank you, Kyle!
