These factors equalize the volatility of the contribution from each component and are normalized to one.\n\nThe month-to-month changes are based on 12-month backward moving averages for all components except the agricultural futures profits index, the Iowa stock market index, and yield spread.  The yield spread and new orders index changes are simple arithmetic changes; month-to-month changes for the rest of the components are computed as symmetric percentage changes.\nStandardization factors are updated annually in August.", "distribution": [{"@type": "dcat:Distribution", "describedBy": "https://idh-be.iowa.gov/api/v1/datasets/1111/columns.json", "describedByType": "application/json", "downloadURL": "https://idh-be.iowa.gov/api/v1/datasets/1111/rows.json", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "downloadURL": "https://idh-be.iowa.gov/api/v1/datasets/1111/rows.csv", "mediaType": "text/csv"}], "identifier": "https://data.iowa.gov/catalog/dataset/1111", "issued": "2026-02-11T22:05:32.521928+00:00", "keyword": ["none"], "landingPage": "https://data.iowa.gov/catalog/dataset/1111", "license": null, "modified": "2026-06-15T09:04:38.864840+00:00", "publisher": {"@type": "org:Organization", "name": "Tax Research Bureau", "subOrganizationOf": {"@type": "org:Organization", "name": "Research & Policy Division", "subOrganizationOf": {"@type": "org:Organization", "name": "Department of Revenue"}}}, "theme": ["Economy & Workforce"], "title": "Iowa Leading Indicator Index Standardization Factors"}
