Statistics and Planning Day, Aban 1, is designated to highlight the importance of statistical data and the role of planning in national development. The day serves as an opportunity to emphasize the collection, analysis, and application of statistics in both large-scale and local decision-making across economic, social, and cultural sectors. On this day, organizations and institutions involved in statistics and planning present their achievements and discuss current challenges in the field. This observance was added to the national calendar in 1380 following a decision by authorities in the field of statistics and planning. The aim was to draw greater attention to the value of statistical data and the necessity of planning in policy-making and sustainable development. Conferences, expert meetings, and educational programs focused on statistics and planning are typically held throughout the country on this occasion. The designation of this day also provides an opportunity to review the current state of the national statistical and planning systems and to propose improvements. Experts and managers use the occasion to share experiences and present statistical reports, supporting efforts to enhance data quality and evidence-based decision-making.
