Maine residents are known as Mainers and Down Easters.
City nicknames can aid in the formation of civic identity, assisting outsiders in recognizing a city, or enticing individuals to a municipality based on its nickname; they can also encourage civic pride and communal solidarity. Nicknames and phrases that succeed in establishing a new community's 'ideology or myth' are seen to have monetary worth. Their economic worth is difficult to assess, but anecdotal evidence suggests that cities that 'brand' themselves by implementing new slogans have seen significant economic gains.
