THIS README IS FOR THE DATA/RAW_DATA/SHAPEFILES/CENSUS_TRACTS DIRECTORY.

THIS DIRECTORY CONTAINS THE FILES WHICH CONTAIN THE SHAPEFILES DATA FOR THE CENSUS TRACTS WITHIN THE STATES THAT CONTAIN THE RELEVANT CITIES: CALIFORNIA FOR LOS ANGELES, NEW YORK FOR NEW YORK CITY AND OREGON FOR PORTLAND.

THE RAW AND MANIPULATED DATA FILES ARE NOT CONTAINED WITHIN THIS ARCHIVED FOLDER BUT THE RAW DATA CAN BE ACCESSED THROUGH THE US CENSUS BUREAU TIGER/LINES SHAPFILES DATA AS DISCUSSED IN DataAccessInformation.pdf AS WELL AS IN APPENDIX F OF MY THESIS AND THE MANIPULATED DATA CAN BE CREATED THROUGH THE R FILES IN THIS DIRECTORY. WHILE WE DO NOT HAVE THE FILES ARCHIVED, WE  DISCUSS THE NAMING CONVENTIONS BELOW AS THEY ARE USED WITHIN THE R SCRIPT.

- CALIFORNIA FOR LOS ANGELES: downloaded from the US Census Bureau TIGER/Line shapefiles as "tl_2015_06_tract" as "06" is the FIPS code for California.
- NEW YORK FOR NEW YORK CITY:  downloaded from the US Census Bureau TIGER/Line shapefiles as "tl_2015_36_tract" as "36" is the FIPS code for New York.
- OREGON FOR PORTLAND:  downloaded from the US Census Bureau TIGER/Line shapefiles as "tl_2015_41_tract" as "41" is the FIPS code for Oregon.

- CensusTracts_final.R: this contains the code that extracts the following for each of the above cities from the state census tract data:
	-- *CityCT.rda: census tracts for city, *, using a combination of the state census tracts and the city boundary shapefiles. Although at times the intersection between these is not clear cut and choices have to be made about which census tracts are included.
	-- *CountyCT.rda: census tracts for the counties that contain the city, *, of interest, for example Los Angeles County contains Los Angeles city.
	-- *CityNB.rda: this contains the neighbourhood structure of the census tracts within the city of interest, *, for the use of interpolation of socio-economic variables, where we only use data from the counties that contain each city, or the city itself if the missing data lies surrounded by other census tracts from the city. These also contain the relevant census tracts as \texttt{sp} objects.
