Census unemployment and the Live Register move together across Irish counties (r = 0.869) — but Tipperary and Meath sit furthest from what their own census figures predict

Line up Ireland's 26 counties by Census 2022 unemployment and by the Live Register, and the pattern is strong: a correlation of r = 0.869. Counties with more people recorded as unemployed in the census also tend to have more people on the Live Register. That is not a surprising finding on its own. What is more interesting is the small number of counties where the two measures disagree by more than the general pattern would predict — and why.

Start with the numbers. Across the 26 counties, the census unemployment rate (persons aged 15+ whose principal economic status is "unemployed having lost or given up previous job," per 1,000 residents, excluding first-time jobseekers) and the Live Register rate (per 1,000 residents, latest available month) move together with a correlation of 0.869. A simple straight-line fit puts the relationship at roughly 2.1 Live Register claimants for every 1 point of census unemployment (slope 2.118) — a ratio, not a one-to-one match, because the two counts are not measuring the same thing.

That relationship holds up under scrutiny. Statsmapped tested whether it was really just a stand-in for something else — bigger counties, more affluent counties, counties with an older or younger population, or simple land area — and it survives all four checks: holding land area constant, the correlation is still 0.858; population, 0.865; affluence, 0.835; age structure, 0.870. Leave-one-county-out resampling puts the relationship at between 0.838 and 0.891 depending which county is dropped — nowhere close to collapsing. By our internal standard for these checks, this one is filed as "tested: supports."

None of that means the Live Register is an unemployment rate, and it is worth saying plainly that it is not treated as one here. The Live Register counts people signing on for jobseeker's payments, and that includes part-time and casual claimants who are not unemployed by any standard definition. The census figure, separately, excludes first-time jobseekers from its count. And the two snapshots are four years apart: Census 2022 against a Live Register reading from July 2026. Put together, a gap between the two in any one county tells you about a difference in what is being counted and when — not that either number is wrong.

That gap is the actual story, and it is worth being precise about what it is: for each county we compared its real Live Register rate against the rate our straight-line fit would predict from its census figure (both in per-1,000-residents terms), and ranked the 26 by how far they land from that prediction. This is a gap from a fitted pattern across counties, not a direct comparison of one county's unemployment against another's — two counties can have nearly identical census unemployment and still land at opposite ends of this ranking, as Tipperary and Meath do (30.9 vs. 30.6 census unemployed per 1,000, despite gaps of +8.5 and -9.1 respectively).

At one end, Tipperary's Live Register rate runs 8.5 per 1,000 residents above what its census figure would predict (30.9 census vs. 37.6 Live Register, against an expected 29.2). Leitrim is next furthest above the line, at +6.1 (36.1 vs. 46.3, expected 40.2), followed by Carlow at +5.8 (38.2 vs. 50.5, expected 44.7), Waterford at +5.6 (37.3 vs. 48.2, expected 42.6), and Cork at +5.2 (27.7 vs. 27.6, expected 22.4).

At the other end, Meath's Live Register rate sits 9.1 per 1,000 residents below what its census figure predicts (30.6 census vs. 19.4 Live Register, expected 28.4) — the largest gap in either direction. Kilkenny follows at -8.0 (32.4 vs. 24.4, expected 32.4), then Cavan at -5.9 (36.5 vs. 35.0, expected 40.9), Donegal at -4.5 (41.3 vs. 46.7, expected 51.2), and Dublin at -3.7 (35.7 vs. 35.6, expected 39.3).

What explains a county sitting well off the line? The honest answer is that we do not know for certain, and the definitional and timing differences described above are the leading candidates rather than proven causes. A county whose Live Register includes more part-time or casual claimants relative to its census-defined unemployed population would show a positive gap of exactly this shape — a plausible general mechanism, though we do not have county-level data on claimant composition to confirm it applies to any specific county such as Tipperary or Waterford. Symmetrically, a county where more first-time jobseekers appear on the Live Register than are captured by the census figure (which excludes them) would tend to show a negative gap, as a general mechanism — again without county-level data to confirm it explains any specific county's result, such as Meath's or Kilkenny's. The four-year gap between the two snapshots (2022 to July 2026) is a further, separate source of drift that has nothing to do with either definition being wrong.

None of this is a claim about which counties have a genuine unemployment problem. It is a map of where the two official counts of joblessness disagree most, and by how much, so that anyone using either number locally — a journalist, a councillor, a jobs agency — knows where the gap is largest before treating one figure as a stand-in for the other.
