Population statistics are numerical data that help us understand the size and characteristics of a group of people living in a specific area, such as a country or city. These statistics can include information about age, gender, ethnicity, and income levels. For example, the U.S. Census Bureau collects data every ten years to provide a detailed picture of the population in the United States. By analyzing population statistics, governments and organizations can make informed decisions about resource allocation, public services, and community planning. For instance, knowing the number of children in a region can help schools determine how many classrooms are needed. This information is crucial for creating a better quality of life for everyone.
