Columbia University · University of California, Los Angeles

Radar chart profiling Columbia University and University of California, Los Angeles on output, citations, h-index, impact, reach and breadth — A profile, not a scoreboard: further out means more of that measure, never better. Each axis is scaled to the larger of the two on a log scale.

This describes the indexed record of each university and nothing else. The two are very often of different sizes, and most of the measures above grow with size, so a larger figure means a larger organisation before it means anything else. Nothing here ranks one against the other. Full detail: Columbia University · University of California, Los Angeles · compare a different pair.

What this page is

This is a description, not a ranking. Two universities are put side by side so the differences between them are visible — how much they publish, how widely it is cited, how far it travels and how it ages. No measure here is presented as better than another, and no overall verdict is drawn, because there is no single question a university comparison answers the way "where should this paper go" is answered for journals.

Reading the chart

The chart summarises six of the measures below. It is a profile, not a scoreboard: further out means more of that thing, never better.

Output — indexed articles attributed to the organisation.
Citations — citations those articles have received.
Depth — the peer-reviewed h-index, which describes the depth of the cited record rather than its recent average.
Impact — the 2-year impact: citations in the last two years per citable item. This is the one axis that does not simply grow with size.
Reach — how many distinct journals cite the work, i.e. how widely it is picked up.
Breadth — how many distinct disciplines the organisation publishes in.

Each axis is scaled to the larger of the two on a log scale. Four of the six grow with size, so a large organisation beside a small one will look larger on most of them — that is the difference in scale being shown, not a difference in quality.
