Table 3 The percentage shortage/surplus in FTE GPs for different area sizes including the surrounding areas ( n = 2,773)

Residents class	Mean FTE GP needed based on the expected demand for GP care	Actual mean FTE GP supply	Mean % shortage/surplus in FTE GP based on needed GP care*	Postcode (n)
1,000-2,500	0.70	0.60	-18.9	553
2,500-5,000	1.58	1.67	5.89	372
5,000-7,500	2.66	2.68	-0.23	251
7,500-10,000	3.84	3.87	0.19	199
10,000-15,000	5.38	5.69	5.19	289
15,000-20,000	7.54	7.91	4.93	200
20,000-30,000	10.49	10.75	2.93	340
>30,000	25.74	28.59	9.59	569

Mean percentage shortage/surplus in FTE GP = ((FTE GP - needed FTE GPs)*100)/FTE GPs needed for every postcode area including the surrounding areas.
