This article from Human Animal Support Services (HASS) has some great tips on how to expand and diversify your foster base. They write, "If we want to better serve our communities’ needs when it comes to animal services, we need to find ways to engage all of our communities."
Easy changes include considering which zip codes represent the majority of your foster families and making efforts to reach out to people in under-represented zip codes, removing barriers to fostering (e.g., think about why you include certain questions in your screening process), supporting pets in foster homes (e.g., provide food or other resources), and being flexible (e.g., consider overnight or weekend fostering). Learn how simple changes can have big payoffs for the animals in your care and the people in your community.
