# CDC WONDER Data as a Service

### About the Dataset

CDC WONDER data as a service: mortality, natality, and cancer statistics from CDC WONDER, delivered as analysis-ready SQL tables on Snowflake and Databricks. Instead of pulling manual exports from the CDC WONDER web tool ([wonder.cdc.gov](https://wonder.cdc.gov), CDC's free interactive query site) one query at a time, you get the same federal statistics — underlying-cause and multiple-cause mortality, natality, cancer incidence, and notifiable-disease counts — as maintained database tables you can join, filter, and trend with plain SQL, refreshed monthly as CDC publishes.

This data ships as part of the [**CDC Open Data Product**](/data-catalog/cdc-open-data-product.md) — 1,500+ CDC datasets in one Snowflake database — so subscribing once covers WONDER-derived statistics plus the broader CDC open-data catalog.

## CDC WONDER Web Tool vs. CDC WONDER as a Service

CDC's own WONDER web tool ([wonder.cdc.gov](https://wonder.cdc.gov)) is free and authoritative — for a single one-off lookup it is the right choice. This product exists for everything the web tool can't do:

|                  | CDC WONDER web tool (free)                 | CDC WONDER Data as a Service                                             |
| ---------------- | ------------------------------------------ | ------------------------------------------------------------------------ |
| Access           | Interactive web forms, one query at a time | SQL on Snowflake or Databricks                                           |
| Automation       | Manual exports; API has strict rate limits | No rate limits; schedule any query                                       |
| Joins            | Not possible across databases              | Join mortality, natality, and 1,500+ other CDC datasets in one warehouse |
| History          | Re-request per query                       | Maintained tables, refreshed monthly as CDC publishes                    |
| Suppressed cells | Handled per-export                         | Consistent handling across the catalog                                   |

## Query CDC WONDER Data with SQL

Discover every dataset in the product:

{% tabs %}
{% tab title="Snowflake" %}

```sql
-- List all available datasets
SELECT table_schema, table_name,
       ROW_NUMBER() OVER (ORDER BY table_schema, table_name) as dataset_number
FROM information_schema.views
WHERE table_schema LIKE 'DWV%'
AND table_name NOT IN ('DATASETS', 'DATASETS_BATCHES')
LIMIT 10;
```

{% endtab %}

{% tab title="Databricks" %}

```sql
-- List all available datasets
SELECT schema_name, view_name,
       ROW_NUMBER() OVER (ORDER BY schema_name, view_name) as dataset_number
FROM cdc_dwv.datasets
LIMIT 10;
```

{% endtab %}
{% endtabs %}

## Who Uses This Data

### Common Use Cases

* **Epidemiology and public-health research** — mortality and natality trend analysis without manual WONDER exports
* **Health-systems and payer analytics** — join county-level mortality against provider and facility datasets
* **Life sciences and actuarial teams** — cause-of-death statistics as a maintained SQL reference

### Frequently Asked Questions

**Can I get CDC WONDER data as a service, instead of using the web tool?** Yes — that is exactly what this product is. WONDER-derived mortality, natality, and cancer statistics are delivered as analysis-ready tables on Snowflake and Databricks, refreshed monthly, as part of the CDC Open Data Product.

**Which WONDER databases are included?** 14 WONDER databases spanning underlying-cause and multiple-cause mortality (from 1999), provisional mortality, natality (from 2007), and cancer statistics — 240+ extracted datasets, growing as CDC publishes new releases.

**How is this different from data.cdc.gov?** data.cdc.gov hosts CDC's open-data catalog; CDC WONDER is a separate query system whose statistics are not available as bulk tables. This product delivers both in one subscription: the open-data catalog and WONDER-derived statistics, side by side in the same database.

**How often is the data updated?** Monthly. Our pipeline monitors CDC for new releases and loads them automatically — no manual refresh needed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dataplex-consulting.com/data-catalog/cdc-open-data-product/cdc-wonder-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
