This compressed file contains three separate data files. 1. Direct Contiguity Master File This file contains the master records of version 3.0. It is the one from which all other files are ultimately derived and to which all future changes will be made. It has a non-directed format in order to prevent asymmetries from accidentally being introduced into the data set. It is written in comma-separated-variable (CSV) format, and the variable names are given in the first record in the file. 2. Dyadic Direct Contiguity This file is derived from the master file and includes annual records for each (directional) pair of states that is directly contiguous. Dyad-years in which direct contiguity is absent are not included in the file to reduce greatly the size of the file. Users may assume that if no record is present for a given dyad-year, no direct contiguity exists between the state pair in that year. It is written in comma-separated-variable (CSV) format, and the variable names are given in the first record in the file. 3. National Direct Contiguity This file is derived from the Dyadic Direct Contiguity file and includes annual records for all states that have a direct contiguity to at least one other state. It is written in comma-separated-variable (CSV) format, and the variable names are given in the first record in the file.
