Among the three well-known seismic belts of the world, ESCAP is the most hazardous region which includes Iran. Besides earthquakes, natural disasters such as floods, droughts, and landslides take the lives of thousands annually in the region and displace hundreds of thousand of people. In Iran, only in the last two decades two major earthquakes have occurred with hundreds of thousand casualties. Before the final stages of reconstruction operations in Manjil and Roudbar quake-ridden areas, another earthquake occurred in Bam district which entirely devastated Bam city and left enormous human and financial damages in more than 20 villages. The research project "Crisis management and socioeconomic consequences of Bam earthquake for rural disaster areas" included a study of demographic consequences with a sample size of 300 rural households. An analysis of macro and micro data showed a significant difference in fertility, migration, mortality, employment, forms of marriage, and income levels. Comparative analyses illustrated a positive natural and absolute growth of population, increased migrations, an incremental trend of fertility, changes in sex ratios, exogamous marriages, heterogamy, and differences in economic, subsistence, and income-generating activity indices, in comparison to the pre-disaster period. A dynamic comparison between demographic processes and previous long-term trends shows a biased order.
