NIH Grant Trends

NIH funding trends show how many grants were awarded and how much money was allocated to a research area over time. A rising project count usually means growing interest from both applicants and review panels, while a flat or declining count may reflect shifting priorities, terminology changes, or consolidation into larger awards.

When you search a keyword on this page, the tool queries NIH RePORTER for all projects matching that term across the years you select. The results are grouped by fiscal year and displayed as line charts (project count), bar charts (total funding), and scatter plots (average award size). Together, these views help you understand whether a field is expanding, contracting, or holding steady.

It is important to compare at least five years of data before drawing conclusions. A single-year spike or dip can reflect reporting delays, one-time initiatives such as ARRA or COVID supplemental funding, or changes in how NIH categorizes projects. The trend interpretation panel above the charts provides an automated summary to help you contextualize the numbers.

Several factors drive year-to-year changes in NIH funding for any given topic. Congressional appropriations set the overall NIH budget, which then gets distributed across 27 institutes and centers. Each institute publishes funding opportunity announcements that signal which research areas they want to support. When an institute increases its emphasis on a topic, more investigators apply and more awards are made.

Terminology evolution also plays a role. A field that was once called "gene therapy" may now appear under "cell and gene therapy" or "genetic medicine." If you search only one term, you may miss related projects that use updated nomenclature. Try searching multiple related terms and comparing the results to get a fuller picture.

External events such as public health emergencies can cause rapid shifts. During the COVID-19 pandemic, NIH redirected significant resources toward infectious disease research, which temporarily reduced funding in other areas. Understanding these context-dependent shifts prevents misreading a short-term dip as a permanent decline in interest.

Trend data can strengthen the significance section of your grant application. If you can show that NIH investment in your research area has grown steadily over the past five years, reviewers are more likely to see your project as aligned with current priorities. Conversely, if funding is declining, you may need to frame your proposal in a way that connects to a growing adjacent area.

Use the opportunity landscape plot on this page to identify which institutions and agencies are most active in your area. This information helps you target the right NIH institute for your application and identify potential collaborators or letter-of-support writers at well-funded institutions.

Remember that trends are one input among many. A growing field also means more competition, while a niche area with stable funding may offer better odds for a well-positioned application. Pair trend analysis with study section preferences, recent RFA/PA announcements, and conversations with program officers for the most complete picture.
