DENVER – Colorado voters decided to join other states by voting to raise the minimum wage in the state, in steps, between 2017 and 2020 after passage of Amendment 70 on Tuesday.

Currently, the minimum wage is $8.31 in Colorado, but under the amendment, it will increase to $12 an hour by 2020.

The minimum wage will be raised to $9.30 in 2017 and will continue to increase. The increase will take a full-time minimum-wage worker’s pay from $17,285 a year to $24,960 by 2020.

With 48 of 64 counties reporting early Wednesday morning, the amendment was passing with 1,244,479 votes (54.4 percent) in favor and 1,044,333 votes (45.6 percent) against.

Labor unions and advocacy groups pushed hard for the measure, especially as the cost of living and housing costs continue to surge in the state, especially along the Front Range.

Numerous business groups, including the Colorado Restaurant Association, fought against the amendment.
