The National Statistical Institute starts pilot testing on the ‘European Health Interview Survey (EHIS) 2025 wave’ project

In June 2025 will be conducted a pilot test of the questionnaire and methodology for the upcoming European Health Interview Survey. The survey is being carried out in the framework of the ‘European Health Interview Survey (EHIS), 2025 wave’ project under Grant Agreement with the European Commission No. 101191410 - 2024-BG-EHIS. The pilot aims at testing the harmonised questionnaire, the developed IT applications and the overall methodology of the survey, which will be conducted in autumn this year.

The testing will be conducted among a random sample of about 720 individuals in 360 households in six districts in the country: Blagoevgrad, Vratsa, Ruse, Targovishte, Haskovo and Yambol. Households will be visited by trained interviewers to conduct personal interviews and complete the questionnaire. The interviewers will identify themselves with an official card and present a letter from the President of the NSI. In each selected household, all persons aged 15 years and older will be interviewed. There is an opportunity for the sampled persons to self-interview by filling in the questionnaire in a web-based application.

The European Health Interview Survey is part of the European Health Survey System, which aims to collect information on the health status, life style (health determinants) and health care services use of the EU citizens. The main objective of the project being implemented is to collect data for the Republic of Bulgaria in accordance with Regulation (EU) 2019/1700 and the relevant implementing and delegated acts, thus ensuring reliable and comparable data at European Union level.

The personal data provided by the respondents will be collected and processed only for the purposes of pilot testing and improvement of the questionnaire and the methodology of the actual survey. Aggregated results will not be published.

Thanks in advance to the households for their cooperation!
