The quality or state of being crowded; the condition of having many people or things packed together.
From 'crowded' + '-ness' (noun suffix forming abstract nouns). This formation developed in English alongside other '-ness' abstractions in the 18th century to describe the feeling or condition of congestion.
The noun 'crowdedness' emerged as philosophers and urban writers in the 1700s tried to describe a new phenomenon: cities were getting so packed with people that observers needed a word for that specific feeling.
