Files and codes contained:

File to convert network codes to city names Network files for each city Ethnicity files for each city Cell assignment files for each city Codes to obtain the mfpt between ethnicities for the adjacency and commuting grapjs

File to convert network codes to city names:

The file csacodes.txt includes the conversion from csa codes to the actual city names

The header is:

csacode;city,state

Network files:

The network files for the adjacency graph can be found are adjcsa/network_.csv where * corresponds to the city CSA code The network files for the commuting graph can be found are comcsa/network_.csv where * corresponds to the city CSA code

It is a directed graph whose heading corresponds to:

source;target;weight

Ethnicity files:

The ethnicity files for the adjacency graph can be found are adjcsa/coloreth_.csv where * corresponds to the city CSA code The ethnicity files for the commuting graph can be found are comcsa/colorethmix_.csv where * corresponds to the city CSA code

The heading for them is

node;ethnicity;probability

The correspondence between the class code and each ethnicity is:

0-->White alone 1-->Black or African American alone 2-->American Indian and Alaska Native alone 3--> Asian alone 4--> Native Hawaiian and Other Pacific Islander alone 5-->Some Other Race alone 6-->Two or More Races

Cell equivalence files:

The equivalence files for the adjacency graph can be found are adjcsa/classequi_.csv where * corresponds to the city CSA code The equivalence files for the commuting graph can be found are comcsa/classequi_.csv where * corresponds to the city CSA code

The heading for them is

census_tract_id;node_id

Codes:

There a total of 4 codes, two for the results on the real city and two for the null-model.

The codes for the real cities are name as adj.c for the adjacency network and com.c for the commuting graph and both can be used by compiling and introducing the csa code of the desired city

make adj ./a csa_code

make com ./com.out csa_code

The codes for the null model are named as adj_null.c for the adjacency network and com_null.c for the commuting graph and both can be used by compiling and introducing the csa code of the desired city

make adj_null ./adj_null.out csa_code

make com_null.c ./com_null.out csa_code
