The state is running these studies. I guarantee you New York State has many good lists of people living in the state. Start with the jury duty list, for example. It pulls data from the DMV, voter registration files, state tax filers, non-driver's IDs such as NYC ID, and more. That covers all the adults. You can get a good list of adults residing in the state to pull your random sample from, and to include the children go get data from the school system and/or just test whatever children live with any given adult that you pick randomly.
