What does it mean if a state is below sea level?

It is incorrect to assume that an entire state can be below sea level. While specific areas within a state may lie below sea level, it is highly unlikely for an entire state's landmass to be submerged. Some regions, like the Netherlands or parts of Louisiana in the United States, have areas below sea level. These regions implement various strategies, including dikes, levees, and pumping systems, to manage water levels and protect against flooding.
