US state meta information and other fun stuff

Project description

US: The Greatest Package in the World

A package for easily working with US and state metadata.

  • all US states and territories
  • postal abbreviations
  • Associated Press style abbreviations
  • FIPS codes
  • capitals
  • years of statehood
  • time zones
  • phonetic state name lookup
  • is contiguous or continental
  • URLs to shapefiles for state, census, congressional districts, counties, and census tracts

Installation

As per usual:

pip install us

Features

Easy access to state information:

>>> import us
>>> us.states.MD
<State:Maryland>
>>> us.states.MD.fips
u'24'
>>> us.states.MD.name
u'Maryland'
>>> us.states.MD.is_contiguous
True

Includes territories too:

>>> us.states.VI.name
u'Virgin Islands'
>>> us.states.VI.is_territory
True
>>> us.states.MD.is_territory
False

List of all (actual) states:

>>> us.states.STATES
[<State:Alabama>, <State:Alaska>, <State:Arizona>, <State:Arkansas>,...
>>> us.states.TERRITORIES
[<State:American Samoa>, <State:Guam>, <State:Northern Mariana Islands>,...

And the whole shebang, if you want it:

>>> us.states.STATES_AND_TERRITORIES
[<State:Alabama>, <State:Alaska>, <State:American Samoa>,...

For convenience, STATES, TERRITORIES, and STATES_AND_TERRITORIES can be accessed directly from the us module:

>>> us.states.STATES
[<State:Alabama>, <State:Alaska>, <State:Arizona>, <State:Arkansas>,...
>>> us.STATES
[<State:Alabama>, <State:Alaska>, <State:Arizona>, <State:Arkansas>,...

There’s also a list of obsolete territories:

>>> us.states.OBSOLETE
[<State:Dakota>, <State:Orleans>, <State:Philippine Islands>]

The state lookup method allows matching by FIPS code, abbreviation, and name:

>>> us.states.lookup('24')
<State:Maryland>
>>> us.states.lookup('MD')
<State:Maryland>
>>> us.states.lookup('md')
<State:Maryland>
>>> us.states.lookup('maryland')
<State:Maryland>

Get useful information:

>>> state = us.states.lookup('maryland')
>>> state.abbr
u'MD'

And for those days that you just can’t remember how to spell Mississippi, we’ve got phonetic name matching too:

>>> us.states.lookup('misisipi')
<State:Mississippi>

Shapefiles

You want shapefiles too? Gotcha covered.

>>> shpurls = us.states.MD.shapefile_urls()
>>> for region, url in shpurls.items():
...   print "%s: %s" % (region, url)
...
county: http://www2.census.gov/geo/tiger/TIGER2010/COUNTY/2010/tl_2010_24_county10.zip
state: http://www2.census.gov/geo/tiger/TIGER2010/STATE/2010/tl_2010_24_state10.zip
cd: http://www2.census.gov/geo/tiger/TIGER2010/CD/111/tl_2010_24_cd111.zip
zcta: http://www2.census.gov/geo/tiger/TIGER2010/ZCTA5/2010/tl_2010_24_zcta510.zip
tract: http://www2.census.gov/geo/tiger/TIGER2010/TRACT/2010/tl_2010_24_tract10.zip

The shapefile_urls() method on the State object generates shapefile URLs for the following regions:

  • state
  • county
  • congressional district
  • zcta
  • census tract

If you know what region you want, you can explicitly request it:

>>> us.states.MD.shapefile_urls('county')
u'http://www2.census.gov/geo/tiger/TIGER2010/COUNTY/2010/tl_2010_24_county10.zip'

Mappings

Mappings between various state attributes are a common need. The mapping() method will generate a lookup between two specified fields.

>>> us.states.mapping('fips', 'abbr')
{u'30': u'MT', u'54': u'WV', u'42': u'PA', u'48': u'TX', u'45': u'SC',...
>>> us.states.mapping('abbr', 'name')
{u'WA': u'Washington', u'VA': u'Virginia', u'DE': u'Delaware',...

CLI

When you need to know state information RIGHT AWAY, there’s the states script.

$ states md

*** The great state of Maryland (MD) ***

  FIPS code: 24

  other attributes:
    ap_abbr: Md.
    capital: Annapolis
    capital_tz: America/New_York
    is_obsolete: False
    name_metaphone: MRLNT
    statehood_year: 1788
    time_zones: America/New_York

  shapefiles:
    blockgroup: http://www2.census.gov/geo/tiger/TIGER2010/BG/2010/tl_2010_24_bg10.zip
    cd: http://www2.census.gov/geo/tiger/TIGER2010/CD/111/tl_2010_24_cd111.zip

Running Tests

CircleCI is set up to automatically run unit tests against any new commits to the repo. To run these tests yourself in a standardized, Dockerized environment, install the CircleCI CLI, and then execute the tests with:

circleci local execute --job build

Alternatively, you can run tests against only your current version of Python, using:

pytest tests
