From Source to Product Signal

Test a Product Idea in Four Steps

CDC PLACES provides consistently modeled health estimates for counties, places, census tracts, and ZIP Code Tabulation Areas. Start with one measure and a few counties from the current release. PLACES values are modeled small-area estimates with uncertainty, not diagnoses or direct local case counts.

1

Check the Setup

  • Python 3.10 or newer
  • A notebook environment such as Jupyter or Google Colab
  • Three county FIPS codes for a bounded comparison
2

Access the Data

  1. 1.Open the current PLACES release and record its year and county dataset identifier.
  2. 2.Choose one documented measure and one prevalence type for a small set of county FIPS codes.
  3. 3.Retain confidence limits and methodology context when comparing the modeled estimates.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install pandas requests

import pandas as pd
import requests

response = requests.get(
    "https://data.cdc.gov/resource/swc5-untb.json",
    params={
        "$select": "locationid,locationname,stateabbr,measureid,data_value,data_value_unit,low_confidence_limit,high_confidence_limit",
        "$where": "measureid='DIABETES' AND data_value_type='Age-adjusted prevalence' AND locationid in('06037','06073','06075')",
        "$limit": 10,
    },
    timeout=30,
)
response.raise_for_status()
counties = pd.DataFrame(response.json())
for column in ["data_value", "low_confidence_limit", "high_confidence_limit"]:
    counties[column] = pd.to_numeric(counties[column], errors="coerce")
counties["retrieved_at_utc"] = pd.Timestamp.now(tz="UTC")
print(counties.sort_values("data_value", ascending=False))

Test a Useful Signal

Compare Modeled Diabetes Prevalence across Three Counties

Compare age-adjusted diagnosed-diabetes estimates and uncertainty for three California counties.

  1. 01Confirm the release year, DIABETES measure definition, county FIPS codes, and age-adjusted prevalence type.
  2. 02Rank the three estimates while showing their low and high confidence limits.
  3. 03Explain that overlapping uncertainty, model inputs, and small-area estimation prevent treating the values as diagnoses, direct counts, or program effects.
