irq - urban rural exploration with oxford access indicators

@mhkhan27 - since the relationship between FCS/medical costs and distance to nearest water may be driven by rural-urban differences (urban centers closer to rivers), perhaps we should also show some comparison/tests with the oxford indicators (distance to health and urban centers?)
