There are two things to be aware of then thinking about and searching for data.
Data and Statistics are inherently very specific, but what you really want to know may not be. There are some terms that we use to describe a state of being or set of people that do not have a singular, clear definition. Think about your topic and the words you are using to see if there are ways to more clearly define what you want to know.
Example: Suicide data could represent non-fatal suicide attempts, deaths by suicide, or both.
When dealing with sensitive topics, it can be hard to get exact statistics due to non-reported incidents, situations where charges were not filed, arrests were not made, individuals choosing not to self-identify, or being unable to recognize oneself as a victim or survivor. Data relies on something that can be clearly identified by a researcher, so you may have to focus on finding an acceptable measure of prevalence over an exact match to your topic.
Example: Domestic violence data often relies on law enforcement's ability to accurately identify and report it, and state laws may differ on how they code and define charges.
