The survey covers the number of crisis events that have occurred on the territory of the Republic of Bulgaria during the reference year by categories, type of events and municipalities (LAU). Main indicators: 

• Number of events by categories and types;
• Number of casulties (human fatalities and injured individuals) - absolute figures and number per 100 000 people
• Public expenditures for hazardous events by use and source of funding - thousand BGN, thousand EUR, % of GDP

Calculation Methods

• Human fatalities from hazardous events per 100 000 people - The number of human fatalities is divided by the average annual population of the respective territorial unit and multiplied by 100 000.
• Injured individuals from hazardous events per 100 000 people - The number of injured individuals is divided by the average annual population of the respective territorial unit and multiplied by 100 000.
• Expenditures for hazardous events as a percentage of GDP - Expenditures by use are divided by the country's total GDP in thousand BGN (at current prices) and multiplied by 100. GDP data is based on the revision as of October 18, 2024.

The NSI’s assessment of expenditures for hazardous events in the ‘General Government’ sector for the reference year includes the following activities from Section VI of the Unified Budget Classification (UBC):

• Management of state and wartime reserves;
• Fire protection;
• Urgent activity to protect the population and the national economy;
• Defense-mobilization preparation, stockpile maintenance and capacities;
• Preventive activities to reduce the harmful consequences of disasters and accidents;
• Elimination of consequences from natural disasters and industrial accidents;
• Volunteer formations for disaster protection;
• International programs and agreements, donations, and foreign aid;
• Other activities for civil protection in the event of natural disasters and accidents;
• Geo-protection;
• Safety and storage of radioactive waste;
• Decommissioning of nuclear facilities.

In the event of an extraordinary crisis during the year, additional expenditures for these events are assessed separately, beyond the activities listed above in the UBC.

• Events and hazards by type (in accordance with SENDAI);
• Unified Classification of the Administrative-Territorial and Territorial Units in Bulgaria (ЕККАТЕ);
• Unified Budget Classification (UBC).
