Data Validations
At Replica, we know customers won't feel comfortable using our data until they trust it. And the most direct way to establish that trust is to validate Replica's data against other known or established sources. That's why we work with agencies, partner firms, and researchers across the country to facilitate independent data analyses to assess and validate the fidelity of Replica's own data outputs. Below, we have shared a few examples of this work. If you're interested in completing your own assessment or validation, please reach out here.
