Here's northern Delaware. As my personal experience attests, the suburbs are very diverse. Asians (and many types of Asians, such as Chinese, Korean, Indian, and even some Middle Eastern) are mixed in with whites very well, especially in the Hockessin and Pike Creek areas west/northwest of Wilmington.
