DETROIT, Nov 5 (Reuters) - JPMorgan Chase ( JPM ) has

invested $2 billion during the past 11 years in Detroit to help

reduce unemployment and boost growth, CEO Jamie Dimon said in an

interview in the city on Wednesday, and the bank plans to roll

out the model in other U.S. cities.

The largest U.S. lender's investments have included $1.8

billion in commercial loans and credit and $200 million in

philanthropy.

"We've seen an increase in consumer accounts, small business

accounts," he said, as well as financing large companies based

in the city.

JPMorgan ( JPM ) plans to add up to 70 employees in Detroit from a

current 80 people working in a virtual call center for its

consumer and auto businesses, the bank said.

Detroit, once the heart of the U.S. auto industry, filed for

bankruptcy in 2013 after decades of population loss, industrial

decline and fiscal mismanagement.

Since then, it has shown signs of recovery, with new

housing, small business growth and increased investment from the

public and private sectors. Several companies, including General

Motors, DTE Energy and Rocket have invested locally.

Detroit has served as a testing ground for JPMorgan's ( JPM )

community investment strategy, and it plans to replicate the

model in Baltimore, Atlanta and Birmingham to expand its

commercial and philanthropic footprint.

"It's the origin story for how we think about our

involvement, engagement and investment in communities," said Tim

Berry, head of corporate responsibility at JPMorgan ( JPM ).

The lender is building a new office in Detroit, scheduled to be

completed next year. In October, it opened a $3 billion

headquarters in New York, which will serve as a model for the

company's future offices worldwide.
