Bed density is also markedly low, with 1.6 beds per 1 000 population in 2013, compared to 4.8 beds per 1 000 OECD-wide: again, the lowest amongst OECD countries. Although per capita total spending is now broadly similar for individuals with and without social security (at MXN 3 429 per capita for those without social security in 2013, compared to 3 505 for IMSS and 3 945 for ISSSTE affiliates), differences in entitlement persist, involving some common and devastating illnesses. Heart attacks in those aged over 60, strokes, dialysis after renal failure, multiple sclerosis and lung cancer are not, for example, covered by SP. Some differences in access are also apparent.
