The study focuses on indicators influencing the development of international tourism, with particular attention to statistical data and the content of several selected indicators affecting the tourism sector, in order to promote tourism development and achieve economic growth. According to the data of the Statistical Agency of Kazakhstan over the past five years, in order to determine the sustainability of the presented indicators and establish their priority, indicators with a strong statistically significant relationship with dependent variables were selected, and the results of data approximation were defined. The relevance of the article lies in the growing international tourism trend and achieving economic growth through the development of sacred tourism by preserving the historical and cultural heritage of the republic and increasing the flow of tourists visiting sacred sites. The study employs methods of statistical analysis, generalization, and comparison to examine the sustainability indicators influencing tourism and to determine their impact. The methods include calculating the arithmetic mean and the weights of normalized values for each direction, as well as conducting statistical analysis and comparison. Summarizing the article, the authors identified the differentiated influence of the selected indicators on overall sustainability, and based on the obtained results, a growth dynamic across the republic is expected. Furthermore, selected indicators for the period 2020–2024 have been determined for conducting scientific research. Based on the results of sustainable development indicators in the country, linear growth has been identified, encompassing each dimension
