TRR 266 Research Data

insol

Research data on insolvency proceedings of German firms

insol is a longitudinal research database of German firm insolvency proceedings and the official filings associated with them. It covers firms and other registered economic entities that can be identified through German register identifiers. We provide two data products:
  • Aggregated daily data on new insolvency cases, grouped by courts and WZ 2008 industry sectors (if available). These data can be accessed freely via our API.
  • Detailed micro-level research data on insolvency proceedings. Available only for non-commercial academic use.

New cases are reported by business day. The line averages reporting dates within the preceding 90 calendar days, including the current date. The data underlying this chart can be obtained via the insol API.

Published research data

Versioned releases

01

Dated releases

New data releases follow the regular collection and processing of insolvency filings. Each release contains normalized Parquet data, a versioned codebook and release metadata.

02

Immutable history

Published releases remain available through the API. Later schema changes do not alter the data or structure of historical releases.

03

Reproducible pipeline

Each release records the code version that produced it. Historical inputs are used to reproduce and verify past releases.
