Tourism statistics play a pivotal role in developing and determining a marketing strategy, strengthening bonds between companies, assessing management decisions' efficacy, and computing tourism in the national economy (United Nations, 2010a). In other words, decision-making requires reliable information to guide rational policies and strategies of development. The scarcity of robust digital databases providing precise, accredited, and reliable information is a common challenge in our nation's tourism industry. Especially, there is currently a shortage of techniques for determining the statistics of domestic travelers. Therefore, this study aims to gather and scrutinize data about domestic travelers through 3 registration points including Entry points of protected areas, electronic toll collection points, and accommodation units in each province by utilizing approaches like document analysis, induction, and deduction. By amalgamating these datasets, we proposed a method for calculating the statistical record of all travelers and tourists of Mongolia who traveled domestically.
