Sub-districts are smaller administrative divisions within a larger district, often used to manage local governance more effectively. They help organize communities and provide essential services, such as education and healthcare, at a more localized level. Sub-districts can vary in size and population, depending on the overall structure of the country they are in. In many countries, sub-districts may have their own local government officials, such as a sub-district head, who oversee the administration and implementation of policies. This system allows for better representation of local needs and facilitates communication between residents and higher levels of government, ensuring that community concerns are addressed.
