2. An Administrative Data Product Longitudinal Employer-Household Dynamics (LEHD) Program Partnership with States Combined existing administrative data and census/survey data to produce new knowledge about jobs, firms, and workers.

3. Data Infrastructure Very large dataset: – 130 million jobs each quarter – About 94% of US jobs Cutting edge confidentiality protection approved by the Census Bureau’s Disclosure Review Board – Noise Infusion – Imputation – Synthetic Data Methods

4. LEHD’s Public-Use Data Products Quarterly Workforce Indicators (QWI) – 30 job-based indicators (e.g. New Hires) – State, county, metropolitan/micropolitan areas – Age, ownership, race, ethnicity, education, industry, firm age, firm size breaks LEHD Origin-Destination Employment Statistics (LODES) – Home-Work relationships – Census block-based (11.1 million census blocks) – Age, ownership, earnings, industry, sex, race, ethnicity, education

5. OnTheMap A free, online, mapping tool for analyzing the LODES data. Basic Goals: – Promote the use of the LODES data – Promote exploration of the data’s spatial dimensions – Create a simple, easy-to-use interface – Show results (maps, tables, visualizations) that provide insight on economic questions.

6. Motivations The idea is to enable users to manipulate the data in a way that allows them to ask questions and answer them and then promote the asking of new questions. We want users to be able to view the data from many different frames of reference in order to generate new insights.
