Sedgwick County is the largest county in Kansas by population and anchors the Wichita metropolitan area. This report maps ownership concentration across 239,107 parcels — the second largest dataset in the entire NPA catalog after St. Louis County — identifying 2,729 clusters with full valuations (land and improvement split) and year-built data for every parcel.
Sedgwick County is the richest Kansas dataset in the NPA catalog — 239K parcels with full valuations and year-built data, enabling both dollar-denominated concentration analysis and pre-1950 housing stock signals.
Largest Kansas county: 239,107 parcels, 2,729 clusters. Sedgwick County is the second largest dataset in the entire NPA catalog, exceeded only by St. Louis County. The sheer scale of the Wichita metro parcel universe means cluster patterns here carry statistical weight that smaller Kansas counties cannot match. With 2,729 clusters identified, this is the definitive ownership concentration map for the Kansas market.
Full valuations with land/improvement split. Every parcel in the Sedgwick County dataset includes appraised values broken down by land value and improvement value. This enables dollar-weighted concentration analysis — identifying not just how many parcels a cluster controls, but the total assessed value under concentrated ownership. Value-weighted rankings often surface different clusters than parcel-count rankings alone.
Year built enabled: pre-1950 housing stock signal. The year_built field is populated across the Sedgwick County dataset, enabling aging-stock analysis. Clusters concentrated in pre-1950 housing may indicate operators targeting older, lower-cost inventory — a common pattern for value-add rental strategies. This field is not available in every NPA county report, making Sedgwick one of the most analytically rich datasets in the catalog.
Wichita dominates with 144K parcels. The City of Wichita accounts for approximately 144,000 of the county's 239,107 parcels. Suburban communities including Derby, Haysville, Bel Aire, and Park City round out the metro. Cluster patterns differ between the urban core and suburban ring, with out-of-state operators present across both segments.
Out-of-state operators present. The Sedgwick County data reveals ownership concentration clusters linked to mailing addresses outside Kansas, confirming that Wichita is on the radar of regional and national portfolio operators. The report identifies every out-of-state cluster with entity counts, parcel counts, and aggregate valuations.
