The Privacy Act of '74 only protects citizens & “green card” holders. That creates a challenge when agencies hold records on both people who are covered & people who aren't In these “mixed systems,” agencies often can’t tell who's currently covered, & therefore entitled to protections under the Act🧵

You can’t have high-quality public data without sustained support. We need stable funding and modern tools to ensure long-term access, preservation, and reliability of public data. Sustainability is the 6th in our Guiding Principles for Public Data. Read them all here: apdu.org/wp-content/u...

APDU Guiding Principles for Public Data
Principle 6: Public Data Systems Are Sustainable
Data systems must be designed for long-term access, preservation, and reliability.
Regular monitoring and oversight help identify risks and ensure continuity.
Even one-time data collections should meet rigorous standards.

APDU@apduorg· Mar 27

To support people and communities, public data quality must be “fit-for-purpose.” In practice, it looks like rigorous collection methods, documentation, and continuous evaluation against established standards. Learn more about our Guiding Principles for Public Data: apdu.org/wp-content/u...

APDU Guiding Principles for Public Data
Principle 5: Public Data Are Fit-for-Purpose

Quality is multidimensional: accuracy, consistency, and representativeness all matter.
Data should support effective policy and research.
Limitations such as missing data and imputation must be clearly documented.

APDU@apduorg· Mar 21

Transparency & openness build confidence in public data. And help us hold the gov't accountable that data is collected, used, & shared in ways that best serve the public. Read why transparency is our 4th principle: apdu.org/apdu-guiding...

APDU@apduorg· Mar 20

Every step of the data lifecycle must be ethical. Respect for all communities and the public good should be at the center of all data practices. When our data systems are accountable, we can identify, address, and correct harms or errors. Learn more: apdu.org/wp-content/u...

APDU Guiding Principles for Public Data
3: Every Step of the Data Lifecycle Supports Ethical Data
Data should serve the public good.
Practices should respect individuals, communities, and data sovereignty.
Goals, methods, limitations, and uncertainty should be communicated clearly to support responsible data use.

APDU@apduorg· Mar 18

When it comes to public data, privacy & confidentiality are non-negotiable. Privacy protections must be built into every stage of the data lifecycle, not ignored or treated as an afterthought. And that’s why it’s the 2nd of our Guiding Principles for Public Data. Read all apdu.org/apdu-guiding...

APDU Guiding Principles for Public Data
Number 2: Privacy and Confidentiality Are Protected
Strong privacy protections build trust and support data quality.
Communities affected by data should be respected and represented in privacy decision-making.
Privacy protections must be built into every stage of the data lifecycle.

APDU@apduorg· Mar 17

Data collected with public resources should be available to the public. That’s why our #1 Guiding Principle for Public Data is all about making sure public data can be easily discovered, understood, and accessed—while still protecting privacy. Read all of the principles: apdu.org/apdu-guiding...

Info card that reads: APDU Guiding Principles for Public Data
1 Public Data Area Accessible
Why This Matters
Publicly-funded data should be publicly available, with appropriate privacy protections.
Data, metadata, and documentation should align with open data standards.
Data access strengthens democracy and innovation.

2025 was a challenging year for public data, but the deep engagement of the data user community has been a silver lining. As we reflect on the past year at APDU, we think a few data points paint a clear picture of the work we’ve done. And we look forward to continuing our work together in 2026.
