As the Kingdom of Saudi Arabia's economy grew in the 1970s and 1980s, so did its healthcare requirements. During this period the MOH oversaw the construction of hospitals in major cities and other health centres in areas with smaller populations. Currently, there are 498 hospitals in the Kingdom. Of these, 286 are run by MOH, 48 by other government sectors, and 164 by the private sector. There are 2,261 healthcare centres run by the MOH and 2,980 private health complexes. In addition, the number of physicians (including dentists) working in Saudi Arabia stands at 113 thousand (3.3 per 1,000 capita). There are 199 thousand male and female nurses, while there are 354 thousand assistant healthcare personnel (including pharmacists and other healthcare assistants). Moreover, the total number of beds in Saudi Arabia's hospitals is 77 thousand (2.25 per 1,000 capita).
