Is Markham a good place to live?
Markham has fewer than 2,500 residents, so it gets subject grades but no overall grade. Its strongest subject is cost of living (A): median sale £149,000, 3.5 years of area income; rent £747 a month. Its weakest is jobs & income (D−): mean household income £42,355; 4.6% of 16 to 64s claim unemployment benefits.
This town's Health Grade uses ONS's small-area life expectancy and healthy life expectancy for 2019 to 2023, and two Census 2021 measures, bad health and disability, adjusted for age. English towns' grades also use OHID's small-area early deaths, hospital admissions and child obesity, which OHID publishes for England only.
