It depends on who hires you to do the data entry but the minimum typing speed required to get hired to do data entry is 50 words per minute but some data entry jobs may require you to be able to type at least 80 words per minute.
If you work for a company in an office doing data entry then you'll need to meet their requirements to be hired as a data entry worker and have a college degree in data entry as well.
You can also find work from home data entry jobs where you work out of your home and do the data entry and can earn as much as $45.00 to $50.00 per hour doing the data entry while working from your home.
You'll also need to have a college degree but if you work from you should only need a minimum typing speed of 50 words per minute which should satisfy the jobs requirements.
