For each call year, how many of every 1,000 text projects use the term.
Type a term. Projam reads it with the corpus’s rules and shows, for each call year, how many of every 1,000 text projects use it.

How the measures on this page are calculated
Rate
The rate per 1,000 projects: a / N × 1,000. A project counts once per year if its application or report text uses the term. N is the number of text projects of that year matching the group and the filters.
Wilson interval
The shaded band is the interval in which the true rate lies with 95% confidence (the Wilson method). With few projects in a year the band widens: a rate from small numbers is not precise. Even at zero matches the band gives a non-zero upper limit.
How the query is read
The term is read with the corpus’s lemmatiser and the build’s Rule Set: for example, organisations is read as organization and wellbeing as well-being. Only the same lemmas match; stop words count; a match never crosses a sentence end or punctuation.
Programme boundary
The vertical rule marks the boundary between the two programme periods. The line is not broken: action types and forms changed between the programmes, so values on either side of the boundary should be compared with care.
Filters
The filters, by the coordinator’s organisation type and country (and by field of education and topic), narrow both numerator and denominator; N changes accordingly.
