Why are FOIA backlogs so long, and how can I find out an agency's current backlog and average response time?

Long waits are one of the most common frustrations with the Freedom of Information Act (FOIA). Understanding why backlogs form, and where to find an agency’s published numbers, helps you set realistic expectations and follow up effectively.

Why FOIA backlogs get long

Under the federal FOIA, an agency generally has 20 business days to respond to a request, though that clock can be paused or extended in certain situations. In practice, many agencies take far longer because of a structural mismatch between demand and capacity:

• Request volume outpaces staffing. Agencies receive far more requests than their FOIA offices can process, and the queue grows year over year.
• Complex and voluminous records. Requests that touch many records, multiple offices, or sensitive material require line-by-line review and redaction, which is slow.
• Consultations and referrals. When records originate with or involve another agency, the request may be routed elsewhere before release.
• First-in, first-out queues. Most agencies process requests in the order received within tracks (simple vs. complex), so older backlogs delay newer requests.

A “backlog” generally means requests that remain pending beyond the statutory response period.

How to find an agency’s backlog and response times

Agencies report these figures publicly, so you do not have to guess:

1. Check FOIA.gov. The site aggregates government-wide and agency-level FOIA data, including pending requests, backlogs, and processing times, and lets you compare agencies.
2. Read the agency’s Annual FOIA Report. Each agency publishes annual statistics covering requests received, processed, backlogged, and average and median days to respond, often broken out by simple and complex tracks.
3. Ask the agency directly. When you submit a request, you can ask for an estimated completion date and your place in the queue.

Use median processing times, not just averages, since a few very large requests can skew the average upward.

A note on state and local records

This covers the federal FOIA. State and local public-records laws have their own deadlines, definitions of “backlog,” and reporting practices, which vary widely. Check the specific statute and the agency’s own guidance for non-federal requests.
