Third Sector Trends is a study of the voluntary sector in local context. As such, it includes all types of registered organisations with income below £25m but excludes major charities with income above £25m as they tend to work on a wider national or international level and their inclusion would skew local level findings.
Income is not evenly distributed. Micro organisations form 36% of the third sector, but they receive less than 1% of sector income. By contrast, the largest organisations command 74% of sector income, but only constitute 5% of organisations.
