Age of consent, explained

What age of consent means

Age of consent is the age at which someone is considered legally able to agree to sexual activity. Below that age, the law treats a person as unable to give legal consent, regardless of whether they said yes in the moment. This is a legal threshold, not a statement about maturity or judgment — it exists so that sexual activity with someone under that age can be prosecuted even if no force or threat was involved.

Why the age varies by jurisdiction

There is no single, national age of consent in the United States. Each state sets its own age through its own criminal statutes, and the number itself is only part of the picture — the surrounding rules (exceptions, offender-age thresholds, penalties) vary just as much as the headline age does. This is why the same set of facts can be treated very differently depending on which state’s law applies. To find the actual rule for a specific state, see our state-by-state guides.

Age of consent vs. close-in-age (Romeo and Juliet) rules

Many states also have a separate, narrower rule sometimes called a “close-in-age” or “Romeo and Juliet” provision. This is not a second age of consent. It is typically an exception or a defense that can apply when two people are close in age to each other, even though one of them is below the general age of consent. These provisions differ enormously in how they work: some remove criminal liability outright, some only reduce the severity of the charge, and some only offer a defense the accused person has to raise in court. See close-in-age exemptions explained for how these mechanisms generally work.

Why a state’s headline number doesn’t answer every question

Knowing a state’s age of consent is a starting point, not a full answer. The same headline age can sit inside very different legal frameworks — one state’s “16” might carry a close-in-age exception and a narrow offender-age limit, while another state’s “16” might carry neither. Two states can list the identical number and still produce very different outcomes for the same facts.

Factors that can change the legal analysis

Depending on the state, the following factors can materially change how a situation is treated under the law:

• The ages of both people involved, not just whether one person is under the age of consent
• The age difference between them, since many close-in-age provisions only apply below a specific gap
• The type of conduct alleged, since different acts can carry different statutes and penalties
• Whether one person held a position of authority or trust over the other, such as a teacher, coach, or caregiver, which can remove close-in-age protections entirely
• Whether force, threats, or coercion were involved, which takes a situation outside close-in-age analysis altogether and into more serious offenses
• Which state’s law applies, since the same facts are analyzed under entirely different statutes depending on jurisdiction

Simple examples

These examples are illustrative only. They are simplified to show how these factors interact conceptually, and they are not legal conclusions about any real situation or any specific state.

• Example: Two teenagers close in age to each other, in a state with a close-in-age exception, may fall outside the criminal law entirely — or may not, depending on the exact age gap the state’s exception requires.
• Example: The same age gap that qualifies for a close-in-age exception in one context can lose that protection if one person is a teacher, coach, or otherwise in a position of authority over the other.
• Example: An age gap that would normally qualify for a close-in-age exception does not apply if force or coercion was involved, since that moves the situation into a different category of offense.

Because small factual differences can change the outcome, none of these examples should be used to predict how a real situation would be handled.

How to find your state’s rules

Because these rules are set state by state, the only reliable way to understand a specific situation is to look at the specific state involved. Our state guides cover all 50 states and the District of Columbia, each researched individually. Federal law can also apply in some circumstances alongside state law; see federal law for that context.
