Research question
How can a manufactured-housing operator use public information about household energy interpretation without stretching a national dataset, program page, or map into a conclusion about one home, community, borrower, or transaction?
Finding
EIA household energy estimates describe defined survey populations and periods; they cannot predict one home's bill without local rates, weather, equipment, occupancy, and building details.
The finding is about evidence scope. It does not establish a home's condition, market value, legal status, compliance, safety, insurability, financing terms, or the likely result of a specific application. Those questions require the relevant property file and an authorized decision maker.
Source record and method
Start with the publishing agency, not a search-result summary. Record the exact page or table, URL, access date, release or effective date, geography, population, unit, and any footnote that changes interpretation. If the source offers a download, retain the original filename and note whether the data are preliminary, revised, estimated, modeled, or suppressed.
| Field |
Required note |
| Publisher |
Agency and program responsible for the source |
| Release |
Edition, reporting period, or map effective date |
| Universe |
People, homes, loans, places, or records included |
| Measure |
Published definition, unit, and exclusions |
| Filters |
Every selection used to produce the result |
| Limits |
Missing coverage, uncertainty, revisions, and local gaps |
Keep the agency's statement separate from the MobileHomeBiz interpretation. A second reviewer should be able to open the same source, repeat the filters, and reach the same extracted value. Preserve earlier extracts when a publisher revises a table or replaces a page. The change history is part of the evidence.
Appropriate use
Public data can frame a research question, describe a defined population, compare like periods, and help an operator decide which local records deserve closer review. Before comparing two figures, confirm that the publisher used the same universe, unit, period, geography, and revision status.
A virtual assistant may maintain citations, download logs, filter notes, and review dates. The assistant should not make lending, legal, appraisal, engineering, insurance, tax, safety, or compliance decisions. If a source category only approximates the business question, label the approximation plainly instead of presenting it as a match.
Evidence limits
Administrative records reflect the purpose and coverage of the collecting program. Surveys may have sampling error, nonresponse, imputation, and disclosure protections. Map products have versions and effective dates. Regulatory pages explain a program but may not resolve local jurisdiction, contract terms, or facts on the ground.
For a property-level decision, pair the public source with the applicable title, permit, loan file, inspection, map determination, utility record, contract, or professional analysis. An apparent trend does not prove a cause. A national average does not set a local benchmark. A missing record does not prove that an event did not happen.
Reproducible quality check
Test all cited links. Confirm that the source title and publisher match the research note. Review definitions before copying a number, and keep units next to values. Record the extraction steps in order. Ask a second person to reproduce a sample. If they cannot, fix the method note before publishing the conclusion.
Set the next review date from an agency release calendar or map revision notice when one exists. Otherwise assign an owner to monitor the source without inventing a future publication date.
