CAGR and market share, defined
Compound annual growth rate, or CAGR, is the steady yearly rate at which a value would grow to go from its start to its end over a period. A 5.78% CAGR means the PR market is projected to grow by about that much each year on average from 2024 to 2029. Market share is the portion of total spending a segment captures, so 61.63% for outsourced agency PR means most PR spending goes to outside firms rather than in-house teams.
Vendor-reported figures, such as Percepture's client observations or OBA PR's AI claims, describe those firms' own experience and should be read that way.
