Militarized Interstate Dispute Locations (v2.0)

This data set records the geographic locations of MIDs in latitude/longitude coordinates, per dispute and per incident. Dispute version 2.0 covers the 1816-2010 period. Incident version 2.0 covers the 1993-2010 period.

MID Location, 1816-2010 (v2.0)

Overview

 

The Militarized Interstate Dispute Location (MIDLOC) dataset details the precise geographic location of Militarized Interstate Disputes (MIDs) in the post-Napoleonic era (from 1816 - 2010), complementing the Correlates of War (COW) Project's considerable empirical data collection. MIDLOC consists of two datasets:

The MIDLOC-A dataset offers a single point location to represent each MID between 1816 and 2010. This location corresponds to the dispute's onset. Following common convention, latitude and longitude point coordinates are recorded for each observation. Latitude is measured as the angular distance, in decimalized degrees (DD), of a point north or south of the equator. Similarly, longitude is measured as the angular distance, in decimalized degrees (DD), of a point east or west of the Prime (Greenwich) Meridian. There are a total of 2,292 individual records in MIDLOC-A. This is comprised of recorded onset locations for 2,208 independent MIDs from the MID v4.2 (Palmer et al. 2015) dataset - approximately 96% data coverage. 1,756 of these 2,292 onsets took place between 1816 and 1992 and 536 between 1993 and 2010. A total of just 84 MIDs remain without a recorded onset location.

The MIDLOC-I dataset offers point locations to represent each MID incident between 1993 and 2010. Following common convention, latitude and longitude point coordinates are recorded for each observation. Latitude is measured as the angular distance, in decimalized degrees (DD), of a point north or south of the equator. Similarly, longitude is measured as the angular distance, in decimalized degrees (DD), of a point east or west of the Prime (Greenwich) Meridian. There are a total of 3,317 individual records in MIDLOC-I. This is comprised of recorded locations for 3,141 individual MID incidents from a combination of the MIDI v4.01 and the MIDA v4.2 (Palmer et al. 2015) datasets - approximately 95% data coverage. 2,093 of these 3,317 incidents took place between 1993 and 2001 and 1,224 between 2002 and 2010. A total of just 176 MID incidents remain without a recorded location.

Dataset

The data are distributed in a flat text, comma-separated-variable (.csv) file. By default under Microsoft Windows, .csv files will open in Microsoft Excel. But the file may be opened in any program that reads text. In the statistical analysis program Stata, the file may be easily loaded using the command “insheet using MIDLOCI_2.0.csv'' or “insheet using MIDLOCA_2.0.csv''

 

Questions and Feedback

The MIDLOC datasets are hosted by Alex Braithwaite, University of Arizona, under the COW Data Hosting Program. In case of questions or concerns concerning the data or coding rules, he may be contacted by email at abraith@arizona.edu.
