Context & Historical Justification

From Systemic Exclusion to Technical Evidence

Historically, persons with disabilities across jurisdictions have been invisibilized in censuses, sectoral statistics, and national development plans. Without disaggregated microdata or quantitative metrics, public policies have operated from charitable welfare rather than the human rights approach established in the United Nations Convention on the Rights of Persons with Disabilities (CRPD).

The IDI was created to transform that reality. It is not just another descriptive narrative report, but an econometric and sociopolitical instrument that calculates the exact gap between institutional rhetoric and daily lived reality. By cross-referencing census, budgetary, legal, and fieldwork data across Ireland, the UK, and Guatemala, the Index reveals structural exclusion and mathematically measures the compliance of public, private, academic, and media sectors.

💡 Why an Index rather than a conventional report? Because data without mathematical weighting dilutes institutional accountability. The IDI establishes a replicable, time-series comparable metric across countries, transforming civic advocacy into incontrovertible technical evidence.

⚖️ Binding Legal Framework: From Medical Charity to the UN CRPD Social Model The index audits compliance across three legal realities: Ireland’s Assisted Decision-Making (Capacity) Act 2015 and UN CRPD Optional Protocol (Nov 2024); the United Kingdom’s Equality Act 2010; and Guatemala’s Decreto 135-96 alongside pending Initiatives 5125 and 6613, auditing the transition away from medical rehabilitation models towards authentic autonomy.

Technical Nature & Architecture

What is the IDI?

The Inclusion and Disability Index (IDI) is a quantitative and qualitative measurement instrument designed to evaluate the degree of inclusion, accessibility, and rights fulfillment for disabled persons across national jurisdictions. Operating as a continuous transnational observatory, it weights institutional capacities, budgetary investment, and structural barriers across four key sectors of society.

Its central purpose is not merely to highlight deficiencies, but to establish an empirical, verifiable, and comparable baseline at municipal, regional, and cross-country levels. Through this observatory, pending state commitments are audited, systematic service provision failures are diagnosed, and actionable recommendations are generated to transform public policy into measurable outcomes.

Empirical Baseline & Critical Evidence

Critical Structural Findings (Ireland, UK & Guatemala)

Official microdata from the CSO Census 2022, Indecon, ONS 2021, Scope UK, and CONADI reveals the systemic depth of exclusion that public policy must close:

1.1M / 16.0M / 1.6M

21.5% in Ireland (CSO 2022) and 24% in the UK (~16M) contrast with severe census under-enumeration in Guatemala (10.2% vs 15% WHO estimate).

37.7% / 28.5% / >70%

Wide employment divides in Ireland (32.6% vs 70.3%) and the UK (53.6% vs 82.5%), and over 70% informal economy in Guatemala (<15% formal jobs).

€9k–€12k / £11.7k / 100%

Annual penalty proven by Indecon in Ireland and Scope in the UK (£975/month), with 100% out-of-pocket costs in Guatemala without statutory living allowances.

407,342 / 4.9M

8.0% of Ireland’s entire population endures severe daily limitations; severe shortfall in statutory Personal Assistance Services (PAS).

<2% Higher Ed / DARE

Barriers in transitions to tertiary education (DAWN / DARE in Ireland), contrasting with less than 2% university access in Guatemala.

EAA 2025 / <5% Transit

Implementation of the EU Web Directive and European Accessibility Act (EAA 2025) versus less than 5% accessible transit in Guatemala.

3%→6% / <0.05% Funds

Public sector employment quota moving from 3% to 6% in Ireland (Disability Act 2005) versus under 0.05% earmarked funds in Guatemala.

Methodological Foundation & Calculation

How is the IDI Calculated?

Originally formulated in Guatemala (iid.gt) and harmonized for European jurisdictions, the IDI is an equilibrium ratio index that contrasts institutional capacity against the structural severity of exclusion.

Standardized Tri-Country Mathematical Model:

🏛️ Numerator: Weighted Institutional Effort (S̄w)

The numerator measures institutional responsiveness across four strategic societal sectors, weighted according to their legal and systemic leverage under the UN CRPD:

S1 (40%) = Public Sector (Primary UN CRPD Duty Bearer)
S2 (25%) = Private Sector (Corporate Labor Market Inclusion)
S3 (20%) = Academic Sector (Higher Education & Research)
S4 (15%) = Media & Communications (Public Awareness & Narrative)

Operational Variables per Sector (V1 to V6):

V1 V1: Strategic / Operational Plan (POA)
V2 V2: Specific Earmarked Budget
V3 V3: Internal Regulation / Reasonable Accommodation Policy
V4 V4: Percentage of Inclusive Employment
V5 V5: Audited Physical & Digital Accessibility
V6 V6: Direct DPO Consultation & Representation

📊 Denominator: Structural Reality of Disability (D̄ = 1/7 ∑ Dj)

The denominator is the unweighted arithmetic mean of 7 empirical dimensions capturing the living conditions and systemic barriers of disabled people:

D1: Employment (EM) — Inactivity and labor market exclusion rate
D2: Education (ED) — Educational attainment divide and support gaps
D3: Poverty & Cost of Living (PV) — Indecon (€9k–€12k) & Scope (£11.7k) price tag
D4: Accessibility (AC) — Physical transit and built environment barriers
D5: Health & Daily Limitation (SA) — Out-of-pocket costs and severe daily limitation
D6: Culture & Identity (CU) — Exclusion from cultural and community participation
D7: Political Participation & DPO Governance (PO) — CRPD Articles 29 & 33 compliance

Index Interpretation & Thresholds

Inclusion Deficit (IDI < 50%)

Structural exclusion and lived barriers severely overwhelm the current institutional response.

Response Parity (IDI = 50%)

Exact equilibrium: the institutional response matches the magnitude of the structural exclusion.

Inclusion Surplus (IDI > 50%)

Institutional investment and systemic response actively outweigh the severity of structural barriers.

⚖️ Why an equilibrium ratio model rather than a simple average? If we used a simple arithmetic mean, a cosmetic improvement in one well-funded sector could mask extreme exclusion in employment or schooling. The parity ratio guarantees that only an integral response proportional to the actual magnitude of structural barriers can cross the 50% threshold.
