But it was the steel crisis of the 1974-1986 period that completely devastated East Chicago, as it did other industrial cities like Gary, Cleveland, Pittsburgh, and the south side of Chicago. East Chicago's population plunged to 47,000 in 1970, 34,000 by 1990, and 29,000 by 2010. Employment at Inland Steel peaked at 25,000 in 1969, and successive layoffs over the next 30 years were devastating to the community; by 1998, only 9,000 were employed at Inland Steel. Inland Steel was acquired by Ispat International in 1998, and both the Indiana Harbor mill and Youngstown Steel mill were absorbed by ArcelorMittal in 2006.
