CORS open.","description":"State trial-court case filings by county, court level and case type: Texas, Washington, Maryland, Indiana and Wisconsin (more states to follow): How many cases are filed in state trial courts, by county, court level and case group, from each state court system's own published statistics. Texas (Office of Court Administration): district, constitutional county and statutory county courts, fiscal years 2023–24 and 2024–25, with district-court filings by case type. Washington (Administrative Office of the Courts): superior courts (criminal, civil, domestic, probate, adoption and parentage, mental illness, juvenile dependency and offender) and district and municipal courts (traffic infractions, DUI, other traffic and non-traffic misdemeanors, civil protection orders, civil and small claims), calendar year 2025. Maryland (Judiciary data dashboard): circuit-court filings by case type (tort, contract, divorce, paternity, juvenile, felony and more) and District Court filings (landlord-tenant, civil, criminal, DUI, traffic citations, peace orders and domestic violence), fiscal years 2012 to 2025. Indiana (Office of Judicial Administration): circuit and superior court new filings by Rule 8 case type (felony, misdemeanor, tort, collection, small claims, eviction, foreclosure, domestic relations, estates, guardianship, juvenile), calendar year 2025 (provisional) beside 2024. Wisconsin (Director of State Courts Office): circuit-court cases opened by county and category (felony, misdemeanor, criminal traffic, traffic, civil, small claims, divorce, other family, paternity, adoption, estates and informal probate, guardianship, commitments, juvenile delinquency and child-welfare), 2020 to 2025. Every record keeps the state's own category names and the numbers added into each group (components), and carries a harmonized group and the practice areas it bears on, so a county's filings can be read as demand for personal injury, family, landlord-tenant, small claims and debt, probate, criminal and DUI, juvenile and traffic work. In every source the counties add up to the state's own printed total where it prints one (Texas, Washington, Indiana, Wisconsin), and the state rows for Maryland are the sum of the counties because the file prints no statewide row.
