A more thorough explanation:

An equalization board is a group of people who work for the local government. Their job is to make sure that taxes are distributed fairly among different areas. They do this by adjusting the tax rates in different districts. This helps to make sure that everyone pays their fair share of taxes.

For example, let's say that there are two districts in a town. District A has a lot of expensive homes, while District B has mostly small apartments. Without an equalization board, the people in District A might end up paying much less in taxes than the people in District B. This would not be fair. The equalization board would adjust the tax rates so that everyone pays a fair amount.

Another example could be a city with different neighborhoods. Some neighborhoods might have more businesses than others, which could affect the amount of taxes they pay. The equalization board would make sure that the tax burden is distributed fairly among all neighborhoods.
