Hi L.-
I've lived in The Woodlands for 3 1/2 years now with my husband and 3 children (6,4, and nearly 1). We came from Chicago and have absolutely loved everything about living here!! As you learn about The Woodlands you'll find that it's divided into several villages and then each village has multiple subdivisions within it. All of the villages are wonderful, however some are older and with older subdivisions you will find a variety of families (retirees, empty nesters, high school kids and then some young families). In the newer villages there seems to be a higher concentration of families with young children. I'm in Sterling Ridge and a lot of the families have elementary and preschool age kids right now. Of course there are all types scattered within the village but the majority seem to have young kids.
Truly, The Woodlands is a wonderful place to live and as far as I can tell, you really can't go wrong with any neighborhood.
Please feel free to send a note if you have any questions, I'll do my best to answer. Also, if you need one I have a wonderful neighbor who is a realtor.
Good Luck,
K.
