IrishTalents · DETE data methodology

How we read Irish employment permit data. A methodology and classification glossary.

This page defines the terms, periods, source files and limitations behind the IrishTalents DETE employment permit directory. It is a research reference, not government guidance or individual immigration advice.

Last reviewed: 14 July 2026

Start with the official source

The Department of Enterprise, Tourism and Employment (DETE) is the official publisher. IrishTalents transcribes and presents public source files; it is not affiliated with the Irish government and does not replace the official publications.

The source archive and workbook links below were checked on 14 July 2026. DETE can publish a later revision, so the number shown on an IrishTalents page can change when the underlying source or import changes.

Official sources

Which DETE publications do we use?

The archive is the source of truth for publication periods and revisions. Each annual publication can link to separate workbooks for nationality, company, county and sector views.

Source provenance has three separate ideas: the source period (the year or month represented), the extraction/import time (when IrishTalents processed it), and revision identity (whether the publisher supplied a newer file). Where a public page does not expose a checksum or import identifier, do not infer that the source is unchanged. Historical pages remain subject to DETE revisions and corrected IrishTalents imports.

Core definitions

What do the counts mean?

The directory describes recorded permit activity. It does not turn those records into applications, approvals, vacancies or forecasts.

Glossary of IrishTalents employment permit count semantics
TermIrishTalents meaningDo not infer
Issued permitsA count supplied by an issued-permit source column or published issued-permit total for the stated period.A live vacancy, current employer demand, job offer, future sponsorship or individual eligibility.
Refused permitsA refused count only when the official source explicitly supplies a refused field with a clear period and denominator.A zero when the field is absent. The current IrishTalents dataset may not expose refusals consistently.
Approval rateNot calculated by IrishTalents from issued counts alone. Official denominator semantics must be verified first.Issued ÷ (issued + refused), unless DETE explicitly defines those fields as a complete comparable denominator.
Distinct companiesCompany entities represented in the relevant IrishTalents source and entity view for that period.A count of brands, offices, vacancies or every legal entity in Ireland.
Periods and comparisons

How do full-year, YTD and comparisons work?

Full year

A year is labelled full-year only when all 12 monthly source periods are available. The directory does not annualise a partial year or treat a missing month as zero.

Year to date (YTD)

A selected month can show YTD as the sum of available January-through-selected-month records. YTD is a partial-year snapshot, not a forecast of the final annual total.

Comparable window

Annual comparisons use the same available month set in both years. This prevents a partial current year being compared with a complete prior year. If the available months differ, the comparison is not treated as like-for-like.

Freshness and revisions

Monthly and annual pages identify the source period and may be refreshed after DETE publishes a new file. A revised historical source can change an earlier total; page freshness should follow the source/import revision, not simply a deployment date.

A monthly page compares its selected month with the prior month and the same month in the prior year when those periods exist. Its YTD label covers January through the selected month. These temporal rules describe the available source records and do not establish a causal trend.

Geography

Why county, city and company location are different

An official county statistic and an enriched company location answer different questions. They must not be merged into one label.

Differences between official county statistics and company location fields
DimensionWhat it representsCoverage warning
Official countyThe geography in DETE's county workbook for the published period.It is not a city total, and it should not be reconstructed from company profile locations.
Company city or locationA company field that may come from the legal entity or enrichment data and may be missing or unverified.A top-company subset can have lower location coverage than an official county workbook.
Public county/sector aggregatesA separately quality-gated read model would be needed for new canonical public claims.Unsupported county/sector public aggregate claims are not yet available on this methodology page. We do not invent totals.
Classification glossary

Which sector and occupation labels are we talking about?

These taxonomies have different owners and purposes. Similar words do not make them interchangeable.

Glossary of DETE and IrishTalents classification systems
LabelMeaningRelationship to other labels
Official DETE sectorThe sector name or code supplied by the official sector source for a permit period.A source sector is not a company industry, NACE activity or SOC occupation.
Company.industryAn industry field attached to a company entity in IrishTalents.It can have different coverage, normalization and update timing from an official DETE sector file.
NACEAn economic-activity classification code, when a company has a usable NACE reference.NACE must not be presented as an official DETE sector alias or a SOC job code.
IrishTalents internal taxonomyInternal macro-sector, subsector or business-type groupings used for product organization when available.It is not an official government classification and is not currently a basis for unsupported public aggregate claims.
SOC 2010An occupation classification used for job-title classification support.SOC classification does not determine permit eligibility, Critical Skills status, sponsorship or legal advice.

DETE labels, canonical aliases and historical mappings can change between source publications. IrishTalents may normalize a display label, but a public versioned mapping table is not currently exposed here. Treat cross-year category comparisons as source-aware, not as proof that every label has remained identical.

Limitations

Company entities and historical activity need context

Legal entity versus brand

DETE files may use a legal entity name while a public brand uses another name. Alias and duplicate handling can be imperfect across historical files. A company page is not proof that every name variant belongs to one current employer.

Verified versus missing fields

Website, LinkedIn, careers URL, location and industry fields may be missing, stale or unverified. Unknown fields should remain unknown; they are not replaced with a guessed location, sector or hiring status.

Historical permit activity

A historical issued permit does not prove a live vacancy, current sponsorship, future permit, job offer, eligibility, approval outcome or willingness to sponsor a new candidate.

Coverage is not completeness

Rankings and subsets can exclude records with missing dimensions or unresolved entities. Do not interpret a company, county or sector list as a complete market census unless the official source explicitly supports that claim.

Use the directory safely

What can you verify on the live pages?

Use the route that owns the question, then read its period and caveat labels before comparing numbers.
