- Public Trust in Government: 1958-2025
Pew Research Center · 2025-12-04 · Evidence period: 1958-2025 · Geography: United States
Population: U.S. adults (survey trend compiled from Pew Research Center and National Election Study data)
Limitations: United States only; it says nothing about trust in Canada or Mexico. Measures trust in the federal government in Washington, one survey question over time.
- Indigenous population continues to grow and is much younger than the non-Indigenous population, although the pace of growth has slowed
Statistics Canada, The Daily · 2022-09-21 · Evidence period: 2021 Census of Population (with 2016 comparison) · Geography: Canada
Population: People enumerated in the 2021 Census who identified as Indigenous
Limitations: Canada only. Statistics Canada notes that growth partly reflects response mobility (people answering the Indigenous identity questions differently from one census to the next), and that some reserves and settlements were incompletely enumerated.
- The 2025 AI Index Report
Stanford Institute for Human-Centered Artificial Intelligence (HAI) · 2025 · Evidence period: 2024 · Geography: Global, with country comparisons
Population: Not a population survey: investment, model and research data
Limitations: Investment figures come from commercial data providers and cover private investment only. Country comparisons say nothing about who inside a country benefits.
- Ending long-term drinking water advisories
Indigenous Services Canada · 2026-09-10 · Evidence period: November 2015 to September 10, 2026 · Geography: Canada (First Nations communities on reserve, south of 60°)
Population: Public drinking water systems on reserve that are funded by Indigenous Services Canada
Limitations: An administrative count of advisories, not a measure of water security: lifting an advisory does not guarantee it stays lifted, and private systems, semi-public systems and communities north of 60° are counted differently or not at all. The page is a live counter, so the numbers move; these were read on September 10, 2026.
- 2025 Report Card for America's Infrastructure
American Society of Civil Engineers · 2025-03-25 · Evidence period: Condition as of 2025; investment need and gap modelled for 2024 to 2033 · Geography: United States
Population: Eighteen categories of U.S. public and private infrastructure
Limitations: ASCE is a professional body that advocates for higher infrastructure investment, so this is an expert assessment against its own criteria rather than an independent audit. Its own pages state the gap as both $3.6 trillion and $3.7 trillion; the economics page and ASCE's news release say $3.7 trillion.
- Billion-Dollar Weather and Climate Disasters: United States summary
NOAA National Centers for Environmental Information · 2025 · Evidence period: 1980 to 2024 · Geography: United States
Population: U.S. weather and climate disaster events with direct losses above $1 billion each
Limitations: The series has been retired, with no updates beyond calendar year 2024, so there is no official figure for 2025 or later; NOAA states the 1980-2024 archive remains authoritative. It counts direct losses only, above a $1 billion threshold that is sensitive to inflation, and draws partly on private insurance data that is not public.
- Literacy, numeracy and adaptive problem solving skills of Canadians: Results from the 2022 Programme for the International Assessment of Adult Competencies
Statistics Canada · 2024-12-10 · Evidence period: Collected 2022 to 2023, compared with the 2012 cycle · Geography: Canada, compared with 27 participating OECD countries
Population: Adults aged 16 to 65
Limitations: Cycle 2 data exclude the territories. The assessment was administered in English or French, so performance can reflect language proficiency as well as skill, which matters in a country with a large immigrant population. Scores are sample estimates, so a precise rank position within the top ten is not established.
- Measuring Canada's economic performance relative to the United States
Statistics Canada, Economic and Social Reports · 2026-03-25 · Evidence period: First quarter 1997 to third quarter 2025 · Geography: Canada relative to the United States
Population: National and business-sector aggregates
Limitations: These are relative index levels rebased to the first quarter of 1997, not absolute productivity levels or a dollar gap, so the base period shapes the headline. Cross-country comparison depends on purchasing-power conversion and hours-worked measurement, both of which are revised.
- Funding Status: Infrastructure Investment and Jobs Act and Inflation Reduction Act
U.S. Government Accountability Office (GAO-26-108434) · 2026-07-22 · Evidence period: Fiscal years 2022 to 2025, status as of September 30, 2025 · Geography: United States
Population: Four federal agencies: EPA, the Department of Transportation, the Department of the Interior and NTIA
Limitations: A financial status report, not an evaluation of what was built. Obligation and disbursement are accounting stages, and capital programmes legitimately lag, so a low disbursement rate is a signal to examine rather than proof of failure. It covers four agencies only.
- Tribal Broadband: Additional Assistance to Recipients Would Better Support Implementation of $3 Billion in Federal Grants
U.S. Government Accountability Office (GAO-24-106541) · 2024-06-24 · Evidence period: Tribal Broadband Connectivity Program round one, completed September 2023 · Geography: United States, Tribal lands
Population: Tribal Broadband Connectivity Program grant recipients; a non-generalizable sample of 16 recipients was interviewed
Limitations: The interview sample is explicitly non-generalizable and covers round one only. The report examines grant administration and financial sustainability. It contains no data on networks completed or households connected, so it cannot show connectivity outcomes.
- 2026 Section 706 Report on the Deployment of Advanced Telecommunications Capability
Federal Communications Commission (FCC 26-55) · 2026-08-14 · Evidence period: Broadband Data Collection deployment data as of June 30, 2025 · Geography: United States, with rural, urban and Tribal lands breakdowns
Population: The whole U.S. population
Limitations: This measures availability, not adoption, affordability or actual subscription: a household counted as served may not have service. It rests on provider-reported data. The Commission's conclusion that deployment is "reasonable and timely" is a policy judgement that reverses the 2024 report's finding, not a change in the underlying data.
- Alaska Native Issues: Federal Agencies Could Enhance Support for Native Village Efforts to Address Environmental Threats
U.S. Government Accountability Office (GAO-22-104241) · 2022-05-18 · Evidence period: Federal funding for fiscal years 2016 to 2020 · Geography: United States (Alaska)
Population: Alaska Native villages and the federal agencies serving them
Limitations: Published in 2022, so it predates later federal climate and infrastructure funding, and the status of its recommendations is not captured here. It is Alaska-specific: it does not describe Tribal Nations in the contiguous United States. Threat counts rest on agency-supplied assessments.
- Worst Case Housing Needs: 2025 Report to Congress
U.S. Department of Housing and Urban Development · 2025-11-20 · Evidence period: Primarily the 2023 American Housing Survey, compared with 2019 and 2021 · Geography: United States, by region and metropolitan category
Population: Very low-income renter households without government housing assistance
Limitations: The survey data are from 2023 and the survey runs every two years. The definition is deliberately narrow, so it undercounts wider cost burden. The report's transmittal letter advances a contested policy interpretation about immigration and demand, which is the Department's argument rather than a finding from the survey data.
- Large Firms With at Least 20 Employees Biggest AI Users
U.S. Census Bureau, Business Trends and Outlook Survey · 2026-05-26 · Evidence period: Collection periods December 14, 2025 to May 3, 2026 · Geography: United States
Population: U.S. employer businesses excluding farms, from a sample of approximately 1.2 million businesses
Limitations: An experimental Census data product. Use is self-reported over a two-week window and says nothing about depth, spending or realised productivity. The headline rate is firm-weighted, so "most firms do not use AI" and "many workers are at firms that do" can both be true. The trend window is under six months.
- Analysis on artificial intelligence use by businesses in Canada, second quarter of 2026
Statistics Canada, Canadian Survey on Business Conditions · 2026-06-11 · Evidence period: Collected April 1 to May 6, 2026, reporting on the preceding 12 months · Geography: Canada
Population: Businesses with employees; 9,251 responses from a sample of 21,105
Limitations: Self-reported adoption with no measure of intensity or outcome: "using AI" covers everything from one chatbot to redesigned operations. The rolling 12-month reference window differs by respondent, and roughly half the sample did not respond. No comparison with the United States is made.
- Artificial Intelligence: Generative AI Use and Management at Federal Agencies
U.S. Government Accountability Office (GAO-25-107653) · 2025-07-29 · Evidence period: Agency AI use-case inventories for 2023 and 2024 · Geography: United States (federal agencies)
Population: Twelve selected federal agencies; eleven publish AI inventories (the Department of Defense is exempt)
Limitations: Counts are self-reported by agencies and cover twelve selected agencies, not the whole federal government. It measures adoption and management practice, not outcomes for the public. Federal AI guidance changed in early 2025, so the two years are not a clean like-for-like trend.
- Climate Change 2022: Impacts, Adaptation and Vulnerability. Chapter 14: North America
Intergovernmental Panel on Climate Change (IPCC), Working Group II, Sixth Assessment Report · 2022 · Evidence period: Assessed literature to 2021 · Geography: Canada, Mexico and the United States
Population: Regional assessment; not a survey
Limitations: An assessment of published literature with a 2021 cut-off. Confidence levels vary by finding and are stated with each one.
- Building Foundations for Tomorrow: Assessing Housing-Enabling Infrastructure Across Canada (National Infrastructure Assessment, Report 1)
Canadian Infrastructure Council · 2025 · Evidence period: Condition data for 2022 · Geography: Canada
Population: Housing-enabling public infrastructure: water, wastewater, stormwater and public transit assets
Limitations: Condition ratings are self-reported by the asset owners, mostly municipalities, rather than independently assessed, and the data are from 2022. The scope is deliberately narrow: roads, bridges, energy, health and school buildings are outside the headline figure. This is the first report in the series, so there is no prior-year baseline.
- NOAA Atlas 15 Pilot Technical Report, Version 1.1.p
NOAA National Weather Service, Office of Water Prediction · 2025-03-25 · Evidence period: Montana pilot domain; present-day estimates for base year 2023 and projections to 2100 · Geography: United States, piloted over Montana ahead of national rollout
Population: Engineering design and floodplain regulation practice
Limitations: The report states its values "are preliminary and intended for comparison and feedback purposes only as this analysis has not completed the peer review process". Results are for the Montana pilot and do not generalise nationally; differences run in both directions. Projections depend on downscaled climate models and emissions scenarios, and the publication timetable has already moved once.
- The Budget and Economic Outlook: 2026 to 2036
Congressional Budget Office · 2026-02-11 · Evidence period: Fiscal years 2026 to 2036 · Geography: United States (federal government)
Population: Federal deficits, debt, outlays and revenues
Limitations: A projection under current law, not a forecast: it excludes appropriation acts passed after 14 January 2026 and any later legislation, and runs only ten years. CBO published data rather than a narrative long-term outlook in 2026.
- Budget 2025: Long-term Fiscal Sustainability
Office of the Parliamentary Budget Officer (Canada) · 2025-12-17 · Evidence period: Baseline 2024-25, projected to 2055-56 · Geography: Canada (federal government)
Population: Federal debt, spending and revenue
Limitations: A 30-year projection resting on Finance Canada's own demographic and economic assumptions, not an outcome. It covers the federal government only, so it says nothing about the provincial and municipal budgets where most infrastructure and service delivery pressure sits.
- Confidence in institutions and the media, 2023
Statistics Canada · 2024-02-13 · Evidence period: Collected October 20 to December 3, 2023 · Geography: Canada
Population: Canadians aged 15 and older in the ten provinces (Canadian Social Survey - Quality of Life, Renter Experiences and Trust)
Limitations: Self-reported confidence from one survey period, and "high confidence" is defined as a score of 4 or 5 on a 1-to-5 scale, which compresses the middle of the distribution. Excludes the territories. Not directly comparable with the U.S. Pew trust question, which asks a different thing.
- Evaluation of the Indigenous Guardians Initiative: Internal review
Parks Canada Agency · 2025 · Evidence period: Activities 2021-22 to 2024-25; fieldwork August 2023 to July 2024 · Geography: Canada
Population: Indigenous Guardians Programs supported through Parks Canada's share of the federal commitment
Limitations: An internal review, not an independent evaluation, and it explicitly did not examine the performance of individual programs, "the aims of which are determined by the values and priorities of Indigenous communities". It covers Parks Canada's portion of the federal investment only. So it documents delivery and a funding-cliff risk, not measured stewardship outcomes.
- NTIA Announces Tribal Broadband Program Reforms to Maximize Tribal Connectivity and Reduce Red Tape
National Telecommunications and Information Administration · 2025-11-12 · Evidence period: Cumulative programme awards to November 2025 · Geography: United States, Tribal lands
Population: Tribal governments and organizations, Tribal Colleges and Universities, Alaska Native Corporations and the Department of Hawaiian Home Lands
Limitations: An agency press release reporting awards made, not construction completed, service activated or households connected. No connectivity outcome can be inferred from it.
- Job mismatch among core working age immigrants with postsecondary education
Statistics Canada · 2026-04-07 · Evidence period: September 2024 and September 2025 Labour Force Survey data combined · Geography: Canada
Population: Workers aged 25 to 54 holding a postsecondary diploma or degree
Limitations: A custom tabulation from the Labour Force Survey, pooling two September snapshots, so seasonal composition is embedded. Overqualification is partly self-reported, and the analysis identifies the mismatch without separating its causes: credential recognition, language, networks and discrimination are not distinguished.
- Employment and Unemployment Among Youth, Summer 2026
U.S. Bureau of Labor Statistics · 2026-08-20 · Evidence period: April to July 2026, compared with July 2025 · Geography: United States
Population: People aged 16 to 24
Limitations: A July snapshot that is not seasonally adjusted, so it is not comparable with monthly headline series, and it covers all 16 to 24 year olds rather than recent graduates. Subgroup estimates are volatile.
- The State of Generative AI Adoption in 2025
Federal Reserve Bank of St. Louis · 2025-11-13 · Evidence period: Real-Time Population Survey, August 2024 to August 2025 · Geography: United States
Population: A nationally representative sample of adults aged 18 to 64
Limitations: Time savings are self-reported, not measured output, and the productivity figure is an upper bound from a stylised model. The authors state plainly that the correlation "cannot be interpreted as causal". Published as central-bank blog research rather than peer-reviewed work.
- Employment Projections: 2025 to 2035
U.S. Bureau of Labor Statistics · 2026-08-27 · Evidence period: Base year 2025, projected to 2035 · Geography: United States
Population: Total employment across 22 major occupational groups
Limitations: A projection, not an outcome. BLS states that "this precision in the data does not account for the inherent uncertainty of predicting long-term changes in the labor market" and applies AI adjustments conservatively. It assumes full employment in the target year.
- Rezoning for Housing: repeal of citywide rezoning
The City of Calgary · 2026-07-21 · Evidence period: September 2023 to August 2026 · Geography: Canada, Calgary, Alberta
Population: Land use across the city
Limitations: A city project page rather than a decision record, and its own banner gives the effective date as August 4, 2024 while its timeline gives August 4, 2026; the timeline date is used here and the discrepancy is noted. The page does not say how many parcels either decision affected.
- Housing starts up 5.6% in 2025 from 2024
Canada Mortgage and Housing Corporation · 2026-01-16 · Evidence period: Calendar years 2024 and 2025 · Geography: Canada, including census metropolitan areas
Population: Housing starts in centres of 10,000 people or more
Limitations: Starts are not completions and not occupancy, and metropolitan figures cover a wider area than a city's own boundary. CMHC attributes national gains partly to record rental construction, so no single municipal policy can be read out of these numbers.
- Five Manitoba First Nations reach major milestones in improving access to safe drinking water
Indigenous Services Canada · 2026-06-23 · Evidence period: To June 2026 · Geography: Canada, Manitoba (Treaty 1, 2 and 5 territories)
Population: Approximately 9,525 community members living on reserve
Limitations: A government news release announcing construction milestones, not an evaluation. It reports one advisory lifted of the five communities named, and no health or water-quality outcome data.
- Active long-term drinking water advisories
Indigenous Services Canada · 2026-09-11 · Evidence period: Numbers as of September 10, 2026 · Geography: Canada, First Nations public systems on reserve
Population: Approximately 5,590 homes and 335 community buildings
Limitations: A live administrative list, so the numbers move; these were read on September 10, 2026. It covers public systems on reserve funded by the department and says nothing about water quality where no advisory is in force.
- 15 Years of Green City, Clean Waters
Philadelphia Water Department · 2026-07-16 · Evidence period: 2011 to 2026, against a programme running to 2036 · Geography: United States, Philadelphia's combined sewer service area
Population: Philadelphia residents in the combined sewer area
Limitations: Self-reported compliance reporting by the water department, not an independent audit. A "Greened Acre" is a regulatory accounting unit for impervious area managed, not a measure of water quality, health or flood risk, and the volume figure is anticipated rather than metered. No Year 15 statutory evaluation plan was published at the time of reading.
- St George Rainway
City of Vancouver · 2025-09-01 · Evidence period: Project engagement and design to 2025 · Geography: Canada, Mount Pleasant, Vancouver, British Columbia
Population: A four-block residential street and its catchment
Limitations: A city engagement page: every benefit is stated as design intent in the future tense, and no measured performance is published. The page's construction dates are out of date, and the City's own project page could not be read directly at the time of writing, so the schedule is not confirmed here.
- U.S. Population Growth Slows Due to Historic Decline in Net International Migration
U.S. Census Bureau · 2026-01-27 · Evidence period: July 1, 2024 to July 1, 2025 (Vintage 2025 estimates) · Geography: United States, by region and state
Population: The resident population
Limitations: These are estimates, not a census, and the Bureau warns that "year-to-year comparisons in the estimates should only be done within the same vintage" because of methodological updates. Part of the measured fall reflects a changed estimation method, and the 2026 figure quoted in the release is a projection.
