Good neighborhoods for young families?

I'm looking in the Boca / Delray area for a community to move to with my two young kids. I'm looking to get a condo or house in the 500-700K range. I know those "Lotus" communities are amazing, but way too expensive. A lot of the more reasonable places that pop up on zillow always seem geared towards retirees.

Does anyone know communities / areas that are good for families and fit my budget?
