BOSTON -- New numbers show how expensive it is to live in Massachusetts -- especially for residents with children.

A new study found that for a single parent with two kids needs about $62,000 to make ends meet in some towns.

Ezra Sandy, a nurse's aide, picked the right profession. Registered nurses are the hottest jobs in Massachusetts for 2010. There are nearly 2,500 vacancies -- according to the Crittenton Women's Union.

Eleven jobs made its list. Technical and scientific sales representatives, followed by computer support specialists are the second and third hottest jobs on the list.

Most of the jobs require a post-secondary education.

"There are only two jobs -- correctional officers and office workers that require only a high school diploma," said Deborah Youngblood of Crittenton Women's Union.
