Vivameda Longitudinal Company Sample: Workforce Evolution for 503 Companies, 1950–2020

A longitudinal panel of 503 companies covering 70 years of workforce evolution, designed to train AI systems on organizational and human capital dynamics. This sample is drawn from the full Vivameda universe of 4.2 million companies and 48 million company-year observations. The dataset was created by Vivameda and last updated in April 2026.

Use Cases

• Analyze long-term workforce evolution patterns based on company-level observations.
• Benchmark predictive models for company dynamics based on the longitudinal panel structure.
• Study human capital trends across decades based on the dataset's stated focus.

Strengths

• Covers a 70-year longitudinal period from 1950 to 2020.
• Provides a foundational sample of 503 companies drawn from a larger universe of 4.2 million companies.
• Explicitly designed to address recency bias in AI systems reasoning about organizations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• The dataset is a sample; the relationship to the full 48-million-observation universe is not detailed.
