The neighborhood history calendar: A data collection method designed for dynamic multilevel modeling

This paper presents a new data collection method, called the Neighborhood History Calendar, designed to collect event histories of community-level changes over time. We discuss the need for and the uses of this method. We describe issues related to the design of instruments, collection of data, and data entry. We provide detailed examples from an application of this method to the study of marriage, contraception, and fertility in rural Nepal. The paper addresses applications of this same technique to other settings and research problems. We also extend the technique to collection of other forms of contextual-history data, including school histories and health service histories. Finally, we discuss how Geographic Information System (GIS) technology can be used to link together multiple sources of contextual-history data.
