The 2021 Regional Disaster Profile Book presents the data of the disasters and the resulting damages from Indonesia’s 34 provinces and 514 districts/municipalities. These districts/municipalities are grouped according to island groups such as Sumatra, Java, Kalimantan, Sulawesi, Bali, Nusa Tenggara, Maluku and Papua. To complement the data on disaster events that occurred in every province and district in Indonesia, this book also displays information on the population disaggregated by age and sex groups living in disaster-prone areas.

The data presented in this report was collected by BNPB throughout 2021 based on reports submitted to the BNPB’s Control and Operation Center (Pusdalops) and validated by the Disaster Information and Communication Data Center. 

To calculate the estimated population that has the potential to be exposed to disasters, geospatial analysis was carried out using population data from the Office of Population and Civil Registration (Dukcapil) data, combined with 2020 population census data from the Indonesian Statistics Agency (BPS) as a proxy to sort population data by gender and age group. The data is then superimposed with disaster threat data from BNPB's disaster risk analysis portal (inaRISK). The results of the calculation generate the estimates of the affected population per age group and sex for each level of disaster threat. 

The UNFPA supported the development of this disaster profile book. Records of disaster events are valuable assets that need to be properly documented, as they can be used as a reference for better future disaster management and a reminder to the community about disaster events that have occurred in their area.
