Recent editions of the Peace and Conflict book series have closely followed and documented the evident turn towards emphasizing disaggregate empirical research on peace and conflict, often focusing attention all the way down to the micro level. Many of these more in-depth studies have contributed to advancing knowledge of major patterns, trends, and causal relationships that are highly relevant not only for scholarly understanding, but also for the needs of real-world application among policymakers and practitioners. Micro-level studies on peace and conflict analyze a rich universe of individual or select country contexts in great depth. One fundamental challenge to the generalizability of findings from micro-level studies concerns variation in measurement, especially as a by-product of divergent theoretical foundations. Many micro-level studies rely on a single existing or compiled dataset for the measurement of any given indicator used in analysis.
