Fentanyl Overdose Data: Counts And Rates In CO

Fentanyl overdose data can look contradictory when one report gives a death count, another gives a population rate, and a third gives a percentage. For readers in CO, the CDC figures discussed here describe the United States, not state estimates. Understanding each measure helps explain what the numbers actually show.

A small decline in one year can coexist with a much larger increase over a decade. A category that mainly reflects illegally made fentanyl can still be broader than fentanyl-only deaths. These distinctions matter when a headline feels reassuring or alarming. You do not need advanced math to understand them. The key is to keep the population, year, drug category, and measurement attached to each figure. National statistics provide context for prevention and care, but they cannot predict what will happen to one person or determine whether someone needs emergency help.

What population and years do the supplied CDC overdose figures describe?

These figures describe overdose deaths across the United States in 2023, with comparisons to 2022 and 2013. They can provide context for women’s support and treatment resources in CO, but they do not supply a CO death count or rate. The related explanation of fentanyl risk with cocaine and methamphetamine addresses exposure and response rather than how national statistics are measured.

The CDC fentanyl page dated June 9, 2025 reports several measures for 2023. The webpage date and the data year have different jobs: one dates the information page; the other identifies when the deaths occurred. Calling these “2025 deaths” because the page carries a 2025 date would mislabel the evidence.

All five figures come from the same CDC national summary, yet they answer different questions. None is a state estimate, a women-only estimate, or a prediction for the current year. Keep the word “approximately” attached where CDC uses rounded figures. The summary does not support treating these values as exact counts or exact percentage changes.

How is a death count different from a population death rate?

A death count tells you how many deaths occurred. A population death rate relates deaths to the size of the population. A percentage of overdose deaths uses a different denominator: all overdose deaths, rather than the population. These measures are not interchangeable.

A denominator is the total used as the basis for a comparison. The same numerator, here a number of deaths, can mean something different depending on what it is compared with. Four terms help keep the distinction clear:

• Count: The number of deaths in the stated place, period, and category. It describes the total loss of life recorded in that category.
• Population rate: A measure that accounts for population size. A basic rate calculation divides a count by a population and expresses the result using a common population unit.
• Share: The portion of a larger total. The reported 69% concerns the composition of overdose deaths, not the percentage of the public who died.
• Percentage change: A comparison with an earlier value. A decrease in a rate describes how that rate changed, not the rate’s actual numerical value.

This explains why the CDC count and rate comparisons can show different percentage decreases without contradicting each other. Counts and population rates do not have the same calculation. Population size can affect their relationship, and the displayed figures are rounded. The summary alone does not establish exactly how much each factor contributed to the difference.

In particular, a 2% decline in a death rate does not mean that 2% of people died, that two fewer people died, or that every person’s risk fell by 2%. It is a relative change in the reported population measure.

Counts remain meaningful because they show how many lives were lost. Rates help interpret deaths in relation to population size. Shares show how much of the overdose total involves a category. One measure does not replace the others; each supplies a different piece of the picture.

What does the synthetic-opioid category include and exclude?

The category is “synthetic opioids other than methadone,” not “confirmed fentanyl-only deaths.” This distinction matters when connecting national evidence with care for substance-use concerns or reading about possible fentanyl exposure through stimulants. A category label must stay attached to the number it describes.

CDC states that the category primarily reflects illegally made fentanyl. “Primarily” means that fentanyl is central to interpreting the figures. It does not make the category identical to a fentanyl-only tally, nor does it establish that fentanyl was the only substance involved in every death.

Three boundaries prevent common misreadings:

• The category is narrower than all opioids. It is a specifically named synthetic-opioid category with methadone excluded. It should not be relabeled as the total for every opioid.
• The wording is deaths “involving” the category. That wording does not establish that a death involved only one substance. It is not a count of deaths proven to involve fentanyl alone.
• The figures concern fatal overdoses. They do not count every nonfatal overdose, every exposure to fentanyl, or every person who used a substance.

CDC also distinguishes pharmaceutical fentanyl, which has medical uses, from illegally made fentanyl. Its page says that the majority of fentanyl-related harms and overdoses are linked to illegally made fentanyl. That broader explanation should not be turned into a claim that the nearly 73,000 figure is an exact count of deaths from one particular source or product.

The category also cannot tell you what was in a particular pill or powder. It provides national information about deaths, not an analysis of an individual drug supply. Preserving that limit keeps the evidence useful without making it more specific than it is.

Why can a small recent decrease coexist with a large long-term increase?

A recent decrease compares two nearby years; a long-term increase compares a much earlier starting point with a later endpoint. A small downward movement does not erase the changes that came before it. Both statements can accurately describe the same national death-rate measure.

CDC reports that the 2023 rate decreased approximately 2% from 2022 while remaining approximately 22 times the 2013 rate. The first comparison describes the latest annual direction within that summary. The second describes how far the endpoint stands above a decade-earlier level.

“Times” and “percent” also mean different things. A rate approximately 22 times an earlier rate is not a 22% increase. The former describes a multiple of the starting value. Replacing “times” with “percent” would substantially change the meaning of CDC’s statement.

The annual decrease should not be dismissed, but it should not be stretched into evidence of a sustained decline. A comparison between 2022 and 2023 cannot establish what happened in every intervening month, every state, or every later year. Likewise, the decade comparison does not mean the rate rose by the same amount each year. Two endpoints do not describe the entire path between them.

Neither comparison, on its own, identifies a cause. A decrease does not prove that one prevention effort produced it. A long-term increase does not prove that one change explains the whole trend. Those are separate research questions requiring evidence beyond the figures on this page.

A careful reading can therefore hold two ideas together: the reported annual measure moved downward, and the reported long-term level remained far above its earlier baseline. Neither fact cancels the other. That is a more faithful interpretation than describing the numbers as either wholly reassuring or evidence that nothing changed.

Why should population data not determine an individual’s emergency response?

National figures cannot determine whether one person is overdosing. Symptoms and the immediate situation require a response, regardless of the direction of a national trend. Understanding when emergency care comes before outpatient treatment serves a different purpose from learning about ongoing substance-use care.

The denominator makes this especially clear. The reported 69% describes the share of overdose deaths involving a drug category. It does not describe the chance that a person using a substance will overdose. The supplied figures do not provide the information needed to calculate that individual probability.

Nor can the national annual decline establish that a particular substance is safer. The CDC page explains that illegally made fentanyl can be mixed into other drugs, and people may not know it is present. An aggregate death statistic cannot establish the contents of a specific product or rule out an opioid emergency.

The immediate response described in the callout follows CDC’s overdose recognition and naloxone guidance. Naloxone is one important step, not a substitute for emergency assistance. Appearing better after it is given does not remove the need for emergency responders. Do not wait to interpret a chart, identify the exact substance, or reach a routine treatment office before calling 911 for suspected overdose.

After immediate safety needs are addressed, national evidence can help explain why prevention education and access to care matter. It still cannot diagnose a substance-use disorder or select a treatment level for one woman.

Women’s Recovery in Denver, CO provides outpatient mental health, trauma, and substance-use programs, including PHP and Intensive Outpatient Program (IOP) care. It does not provide onsite detox, residential treatment, inpatient care, or emergency overdose treatment. For nonemergency information, explore current outpatient programs or contact Women’s Recovery at 833.754.0554. An individual assessment, rather than a national statistic, guides recommendations about care.

Frequently asked questions

Are the supplied CDC numbers specific to CO?

No. These figures describe the United States in 2023, with comparisons to 2022 and 2013. They do not provide a CO death count, state population rate, or women-only estimate. The CDC webpage’s June 2025 date is also different from the year in which the reported deaths occurred.

Does a percentage of overdose deaths describe an individual’s chance of overdose?

No. A percentage of overdose deaths describes how a category contributes to the total number of overdose deaths. It does not describe the probability that a particular person will overdose. Those calculations use different denominators, and the supplied national figures cannot establish an individual’s risk or the contents of a particular substance.

Is the synthetic-opioid category identical to confirmed fentanyl-only deaths?

No. CDC names the category synthetic opioids other than methadone and says it primarily reflects illegally made fentanyl. That is not the same as a fentanyl-only tally. The wording deaths involving the category also does not establish that fentanyl was the only substance involved in every reported death.

Does a national decline mean suspected overdose can wait?

No. A national decline cannot rule out an emergency in one person. If someone cannot be awakened or has slow, shallow, or difficult breathing after substance use, call 911 immediately. Give naloxone if available, follow its product instructions, and stay until emergency help arrives. Do not wait for certainty about the substance.
