Strategic planning is one of the most important factors that can improve the organization itself, and direct it to the right business path and development. Through strategic planning, an organization determines the direction of its business. On this paper we deal with demographic factors and their impact on the strategic planning of preschool. The key task of strategic planning is to achieve the set goals. Through the process of strategic planning, the preschool institution determines its goals, priorities and strategies, and defines measures to assess the success of achieving these goals. Strategic management is a continuous process that enables the maintenance of the organization as a whole and is manifested as such through a series of chapters. The strategic management process itself begins with an analysis of the environment to identify strategic factors (internal and external) that will determine the future of the preschool. To manage the environment, the principals / founders of the preschool use many management tools. The strategic plan must have a defined vision, mission, values, policies, strategic goals and strategies; which also represent the basic elements of the strategic plan. The process of methodological approach to developing a strategic plan begins with defining the mission and vision, followed by environmental analysis (external and internal), and the results are then entered into the PESTE analysis after which policies and values are defined set goals to be achieved. At the very end, from the obtained results, the strategic goals of that strategy are determined, which represent the way to achieve those goals. In this paper, I will focus on demography and demographic factors and their impact on preschool institutions in the Republic of Croatia.
