======================

Mapping and analyzing local business data from the Census Bureau

This the repo for the API that exposes [LODES](http://lehd.did.census.gov/onthemap/LODES7/LODESTechDoc7.0.pdf) via a JSON api.

The JSON API is served via a flask app. A copy is currently living on [heroku](http://enigmatic-fjord-3697.herokuapp.com/). The database is [MongoDB](http://mongodb.com/). The API and its contents live in `/web`.

You can see an example of each item in the collection in `/data_notes/example_data.json`. The data notes folder contains info on the dataset.

The scrapers are live in `/scrapers`.

Each datapoint represents a census block.

We would like to build an API that allows you to query the census data without having to download entire CSVs.

### Installation/Requirements ###

In order to setup the Census API, you must have a installed copy of [mongoDB](http://mongodb.org) (Version 2.4 or greater) and at least 200 gb of free space.

By setting the environment variable `MONGO_HOST`, you can specify which database `scrapers/fetch_and_load.py` will load into. If this is unset, it will automatically use localhost. You can chose a particular state by calling the program along with a command line argument of a state abbreviation. If no command line argument is supplied, it loads the entire dataset.
