KFF State Health Facts & Health Costs Data
Data.gov – Medical Supplies Catalog Search
Where the fields line up
No shared field names. These two answer different questions.
| Field | KFF State Health Facts & Health Costs Data | Data.gov – Medical Supplies Catalog Search |
|---|---|---|
Location | U.S. state name or the 'United States' national aggregate row - the geographic join key, with the national row separable so aggregate arithmetic never double counts. | not in this set |
Medicaid/CHIP Child Enrollment | Number of children enrolled in Medicaid/CHIP for the given month and state - the numerator of the enrollment mix. | not in this set |
Total Medicaid/CHIP Enrollment | Total Medicaid and CHIP enrollment of all ages for the same state-month - the denominator against which the child share is computed. | not in this set |
Child Enrollment as a Percent of Total Medicaid/CHIP Enrollment | Ratio of child enrollment to total enrollment expressed as a decimal fraction, recomputable from the two count fields on the same row. | not in this set |
title | not in this set | Dataset title as supplied by the publishing agency. |
description | not in this set | Agency-written abstract of the dataset - scope, method and contents in free text. |
publisher.name | not in this set | Publishing agency or organization name, CMS down to a single state portal. |
accrualPeriodicity | not in this set | ISO 8601 frequency code for the update cadence the publisher declares, e.g. R/P1Y for annual. |
distribution[].format | not in this set | File format of each distribution - CSV, JSON, XML, XLSX and kin. Blank on some top CMS cards in testing; confirmed per record at sample time. |
distribution[].accessURL | not in this set | API or landing-page pointer for the distribution, back at the owning agency. |
distribution[].downloadURL | not in this set | Direct file pointer for the distribution. |
describedBy | not in this set | Pointer to the data dictionary or methodology documentation the agency publishes for the record. |
What each contains
Pick by fit, not by loyalty.
| KFF State Health Facts & Health Costs Data | Data.gov – Medical Supplies Catalog Search | |
|---|---|---|
| Documented fields | Location plus paired count and percentage columns on every indicator | Eleven catalog attributes from title and abstract through publisher, periodicity and contact point |
| Field types | Counts (35,381,450 children enrolled nationally), decimal shares (0.4790), state labels (Alabama) | Strings and codes: agency names, ISO 8601 rhythm codes (R/P1Y), bureau and program classifications |
| Signature fields | Total Medicaid/CHIP Enrollment (73,871,024 nationally); Child Enrollment as a Percent of Total | title of each cataloged dataset; accrualPeriodicity declared by the publishing agency |
| Shared concepts | A location key and an implicit period stamp on every row | Publisher and subject attributes scoping each dataset to places and periods |
| Overlap verdict | Near-zero literal overlap: one set of columns holds measurements, the other holds descriptions of datasets. | They complement; they do not substitute. |
What each does better
KFF State Health Facts
Finished numbers, zero assembly. Every indicator arrives as a complete geography-by-metric table: raw counts paired with derived percentages, several time periods stacked on one page, a national aggregate beside each state. The Medicaid/CHIP picture is immediate - 35,381,450 children enrolled nationally against 73,871,024 total enrollees, a 47.90% child share, set against Alabama's 71.78% - with no joining or percentage reconstruction left to you.
Stratification aimed at policy questions. Selected indicators break out age groups, race and ethnicity, or individual months, which turns cohort sizing - children covered by state, enrollment shifts by month - into a filter operation rather than a modeling project.
Depth in time where it matters. Current-year snapshots sit next to multi-year and monthly histories in the same tables; the child-enrollment indicator alone stacks 7,844 rows of monthly state observations, enough for pre- and post-pandemic trend lines without archive hunting.
Citable by default. KFF is one of the most widely cited compilations of U.S. state health-system statistics, so a figure lifted from it survives scrutiny in a board memo.
Data.gov – Medical Supplies Catalog Search
Universe size. 552,271 cataloged datasets searchable as one index, from federal desks down to city halls and tribal offices - no editorial ceiling on what a supplies query can surface.
Supply-chain specificity. The ranked leads are working documents: CMS durable medical equipment utilization by referring provider, by supplier, and by supplier and service - the records that show who referred, who billed and what services actually moved.
Metadata that travels. Each DCAT record carries the publishing agency, its declared update rhythm, federal bureau and program codes, a named contact point, and pointers back to the owner's own files - enough to triage a dataset before anyone commits to it.
Faceted narrowing. Organization, organization type, tags, modified-date windows, a geographic bounding box and a files-only toggle cut half a million records to a working shortlist. The honest limits: distribution-format fields came back blank on the top CMS results in testing, and result totals must be inferred by walking the pagination cursor.
Where they're equivalent
- Same slice, same verification. Both live in Health Care Services, both publish verified field dictionaries with examples, and both post 7/10 on Datadory's rubric.
- Aggregates all the way down. Neither names a patient, a claim or a supplier's customer: KFF stops at state and demographic stratum, the catalog at dataset descriptions.
- US-scoped. KFF maps the fifty states plus DC and territories; the catalog indexes US publishers only. Neither covers a health system abroad.
- No literal field overlap. The shared skeleton is conceptual, not columnar - a label, a period, a place, a publishing authority. Join them in a model, never in a spreadsheet key.
The verdict
Verdict: sample both, pick by fit - they are different instruments pointed at the same industry.
Take KFF State Health Facts when the deliverable needs numbers today: benchmark tables for coverage, enrollment, workforce or spending across all fifty states, ready for a memo, a dashboard or a model feature set. Take Data.gov – Medical Supplies Catalog Search when the job is discovery on the supply side: enumerating which agencies hold supplies data - CMS, VA, Defense, the states - before anyone commits to a vendor list or a market map.
Three quick tests settle most cases. Need a citable statistic for every state this afternoon? KFF. Need to find every federal corner holding durable medical equipment activity? The catalog. Need the measurement and its provenance in one project? That is the pairing, not a choice.
Sample both, pick by fit. See KFF State Health Facts & Health Costs Data · See Data.gov – Medical Supplies Catalog Search
Or take both in one feed
Yes - sequentially rather than side by side. Start wide with the catalog: establish which agencies hold supplies-relevant data and what each declares about itself. Then reach for KFF to quantify the demand environment those datasets operate in - enrollment, coverage and spending benchmarks for every state in a distributor's footprint.
Two cautions from the records. First, no join keys exist between them: one keys on state names and indicator slugs, the other on dataset identifiers, so any bridge is a mapping you maintain. Second, vintages differ by construction - KFF tables pair current snapshots with deep histories, while catalog records simply report what each agency declared - so date-stamp everything before it reaches a deck.
Datadory delivers either side daily, weekly, or hourly - your call. Or take both in one feed.

Fair questions
Is KFF State Health Facts better than Data.gov – Medical Supplies Catalog Search?
Better for different jobs. KFF wins anything needing finished statistics: 843 curated indicators, one table per metric, all fifty states plus a national aggregate, with monthly series such as the 7,844-row child-enrollment panel. The catalog wins breadth: 552,271 indexed datasets with CMS durable medical equipment utilization files ranked on top. One holds the measurements; the other holds the descriptions.
Do the two datasets cover the same ground?
No, and that is why comparing them is useful. Their field dictionaries barely intersect: KFF publishes numeric indicators keyed by state and period, while the catalog publishes descriptive metadata - titles, abstracts, publishers, periodicity declarations - about datasets held elsewhere. The only shared concepts are structural: a label, a time stamp, a place and a publishing authority on every record.
Which one is bigger?
Depends on the axis. The catalog dwarfs KFF on records: 552,271 datasets from thousands of publishers, of which the supplies query returns a ranked subset led by three CMS files. KFF wins on curated depth: 843 indicator tables, each internally consistent, single panels reaching 7,844 rows. Breadth versus coherence - pick by which your project starves for.
How current is the material in each?
KFF pairs current-year snapshots with multi-year and monthly history inside the same tables, so recent and longitudinal figures arrive together. The catalog's currency depends entirely on each publishing agency: every record carries the owner's declared update rhythm and last-modified marker as documented fields. Either way, Datadory delivers daily, weekly, or hourly - your call.
Can I get both KFF State Health Facts and Data.gov – Medical Supplies Catalog Search from Datadory?
Yes - sample both and pick by fit, or take both in one feed. Each arrives normalized to its documented field dictionary with sample rows for validation, on the delivery schedule your workflow sets, alongside the rest of the health care services catalog.
