Insurance awareness for different insurance branches in the insurance sector in Turkey is increasing day by day, and the number of policies produced in the sector is increasing day by day. In this context, with the aim of evaluating the insurance indicators that increase in quality in terms of quantity and revealing a performance table for the sector, in the study, a list of the top 14 companies in the market share ranking according to the total premium production in the insurance sector, based on some indicators selected between 2016-2019 activity analysis was carried out. Data envelopment analysis was used as the analysis method. As a result of the study, it has been observed from the analysis results that although the efficiency levels of the companies, which are in the top ranks according to the total premium production in the years examined, are generally at good levels, in some years, the opposite process has also been experienced. Accordingly, companies should increase their profitability and premium production by using their employment numbers and insurance policy numbers more efficiently. [ABSTRACT FROM AUTHOR]
