The average size of GP practice lists has risen as practices have closed and merged at breakneck speed in recent years, while the patient population has increased.
Despite the trend towards larger practices, however, there remains significant variation between CCG areas in practice size.
Analysis by GPonline shows a four-fold difference between the lowest median practice list size for a CCG and the highest - from just 4,299 across the 26 practices in NHS North East Lincolnshire CCG to 16,927 across the 14 practices in NHS Canterbury and Coastal CCG.
