Based on 2015 data from the Health and Social Care Information Centre - now known as NHS Digital - all but 3.5% of GP practices operate under GMS or PMS contracts.
Around 62.5% of practices operate under GMS contracts, 34% under PMS, and 3.5% under APMS deals.
Analysis by researchers last year suggested that traditional practices operating under GMS or PMS deals perform better than APMS providers. Zoom in on the map below to find out about contract types in different parts of England, or search for the town or region you want to see in detail.

However, analysis by GPonline found that the small number of APMS practices that had been inspected by the CQC by November 2015 were three times as likely as their GMS or PMS counterparts to receive an 'outstanding' rating.
GMS contracts are subject to the tightest rules governing who can hold them, with only GPs, GP partnerships or limited companies involving GPs eligible.
PMS contracts can be held by GPs, other NHS employees or limited companies involving either GPs or NHS employees.
Time-limited APMS contracts, however, can be held by private providers including limited liability companies. The prevalence of this type of contract looks set to increase as cash-strapped traditional GP practices are increasingly forced out of business and replaced by short-term providers.
GPonline reported last month on an Essex GP practice - rated outstanding by the CQC - that was set to be taken over by private provider Virgin because it faced £400,000 cuts under a PMS contract review.
NHS England has refused to reveal how much Virgin would be paid to run the practice, but a spokeswoman admitted that APMS deals often involved higher funding because they were time-limited.
