I believe Clifton Park-Halfmoon is more family oriented, as both are completely/largely served by the good Shenendehowa SD. They are growing towns and some of that could be due to the proximity to Global Foundries in Malta.
There looks to be an animal shelter in nearby Ballston Spa, which is the county seat.

Clifton Park more upper middle class, as the town's median household income is/was $108,116 according to US Census 5 year information. Halfmoon was $87,169 during that same period.
Hopefully, others will chime in with more specific information.
