What's Actually in a Death Certificate: Every Field and Who Supplied It

A death certificate is often the first document a genealogist pulls, and for good reason. A single 20th-century certificate can carry the deceased’s date and place of death, cause of death, birth date and birthplace, age, occupation, marital status, surviving spouse, parents’ names, parents’ birthplaces, Social Security number, and the place of burial. In one page it can point you backward two full generations and forward to the next record you need. That is why it is so valuable, and also why it is so easy to misuse.

The catch is that a death certificate is really two documents stapled together. One half is filled out by a medical professional and is highly reliable. The other half is filled out by a funeral director using facts supplied by a grieving relative, and its accuracy depends entirely on how well that one person knew the deceased. Understanding which half you are reading is the difference between a solid genealogical conclusion and a confident mistake. This guide walks through everything a death certificate contains, who supplied each piece of it, and how professional genealogists use the good parts without being led astray by the weak ones.

What information does a death certificate actually contain?

Most modern U.S. death certificates follow the same template because states adapt the U.S. Standard Certificate of Death maintained by the CDC’s National Center for Health Statistics. The exact layout varies by state and by decade, but the categories are remarkably consistent.

A death certificate typically records:

• Identity and demographics: full name, sex, Social Security number, date of birth, and age at death.
• Place facts: place of death, usual residence, and often birthplace.
• Family: marital status, name of surviving spouse (frequently the wife’s maiden name), father’s name, and mother’s maiden name.
• Life details: occupation, industry or kind of business, and sometimes the informant’s own name and relationship to the deceased.
• Death facts: date and time of death, and whether an autopsy was performed.
• Cause and manner of death: the medical chain of events and the legal classification of how the death occurred.
• Disposition: method of disposition (burial, cremation), cemetery or crematory name, and the funeral home and licensed funeral director.

Social Security numbers generally appear only from 1950 onward, which is a useful dating clue in itself. Older certificates carry fewer fields, but even a spare 1910 form usually names the parents, which is the piece genealogists want most.

Who supplied each piece of information, and why it matters

This is the single most important thing to understand about the document. According to FamilySearch, “other than the date, time and place of death, all other information on a death certificate is taken from what is supplied by the informant.” In other words, most of the biographical detail is only as good as the memory of the person standing in the funeral home.

The certificate is completed by two different people with two different jobs. The medical certifier, usually the attending physician or, in unnatural deaths, a coroner or medical examiner, completes the date, time, cause, and manner of death. The funeral director completes the demographic half using information from an informant, who is usually a close family member. The order of preference for that informant runs spouse, then parent, then child, then another relative, then any other person with knowledge of the facts.

Here is how the reliability breaks down field by field.

The pattern is clear. The facts a doctor witnessed are strong. The facts a grieving child recited about a grandparent born decades earlier in another country are the ones most likely to be wrong.

How does the cause-of-death section work?

The cause-of-death section is the most misread part of the certificate, and it is built as a specific two-part structure. As the CDC and the StatPearls clinical reference on death certification explain, Part I reports the chain of events that led directly to death, and Part II reports other significant conditions that contributed but did not cause the fatal sequence.

Within Part I, line a holds the immediate cause, the final disease or complication that directly caused death. The lines below it work backward through the sequence, and the lowest line used holds the underlying cause, the original disease or injury that set the whole chain in motion. For a genealogist, the underlying cause is usually the historically meaningful one. “Cardiac arrest” on line a tells you almost nothing, because every death ends in the heart stopping. The “arteriosclerotic heart disease” listed three lines down is the real story, and reading only the top line is a classic error.

What is the difference between cause of death and manner of death?

Cause of death is a medical finding. Manner of death is a legal classification, and the two answer different questions. The cause explains what biological process ended the life. The manner explains the circumstances that produced it, and it is chosen by the certifier from a fixed set of options: natural, accident, suicide, homicide, and undetermined. Some jurisdictions add “pending investigation” while a case is open.

This distinction matters for family history because manner of death is where the human drama often lives. A manner marked “accident” can send you to a coroner’s inquest file or a newspaper account. A manner marked “homicide” can open court records. The certificate is frequently the thread that leads to a much richer set of documents, from coroner files to newspaper accounts that corroborate and expand what the form only hints at.

Why is the informant the key to everything?

The informant determines how much of the certificate you can trust, so identifying that person is a real part of the analysis, not a footnote. A surviving spouse who lived with the deceased for forty years is a strong informant for a birthplace. An adult grandchild handling arrangements for a grandparent who immigrated as a child may be guessing at the names of great-great-grandparents they never met.

Consider a common and entirely illustrative situation. A certificate lists the deceased’s mother’s maiden name and her birthplace as “Germany.” The informant was a son who never met his grandmother. Later research in church and civil records shows the mother was actually born in a village in what is now Poland, in a region that was part of the German Empire at the time. The son was not lying. He gave the best answer he had, filtered through shifting borders and a name he had only ever heard spoken. Errors like this are the norm, not the exception, and they are exactly why the parents’ birthplaces are the weakest field on the form.

How far back do death certificates go?

Statewide death registration in the United States is a relatively recent system, which sets a hard limit on how far this record type can take you. Massachusetts began statewide registration first, in 1841, and New Mexico was last, in 1920, with most states falling somewhere between 1880 and the 1910s. A few large cities kept municipal death records much earlier, Boston reaching back to the 1600s and New Orleans to the late 1700s, but for most American families the reliable certificate era begins around the turn of the 20th century.

Before statewide registration, the death record you are looking for may not exist as a certificate at all. In that gap, church burial and death registers often carry the same facts, and probate files, cemetery records, and mortuary ledgers fill in the rest. Knowing when your state’s registration started tells you immediately whether to search for a certificate or to pivot to a substitute.

How do genealogists use a death certificate without being misled?

The professional method is correlation. You never treat a single field on a death certificate as proven fact; you treat it as a lead and then test it against independent records created closer to the event it describes. A birth date on a 1935 death certificate is a claim about something that happened in 1858, recorded by someone who was not there. A baptismal record from 1858 is contemporaneous evidence. When they agree, confidence rises. When they conflict, the older record usually wins.

This is why a death certificate is best read alongside other sources rather than alone. The parents’ names on the certificate point you toward a birth or marriage record that can confirm them. The stated age helps you locate the family in an earlier census, and census records let you watch a household change across decades even though they were also filled out from memory. The occupation may connect to city directories or employment records. The certificate’s job is to open doors, and the researcher’s job is to walk through them and verify what was behind the door.

Who can actually obtain a certified death certificate?

Access is restricted, and the rules depend on the state and your relationship to the deceased. Vital records are not public documents that anyone can order. In Minnesota, for example, Minnesota Statutes section 144.225 limits certified death records to a defined set of people, including the spouse, child, grandchild, parent, grandparent, or sibling of the deceased, along with the personal representative of the estate and anyone who can show the record is needed to protect a personal or property right. A certified copy costs $13 for the first and $6 for each additional copy, per the Minnesota Department of Health vital records office.

Genealogists usually distinguish between the certified copy needed for legal purposes, such as settling an estate or proving a relationship for a citizenship claim, and an informational or uncertified copy that is often adequate for research. This access question is closely tied to the concept of tangible interest and who is legally allowed to request a record, and it frequently determines which living relative should be the one to sign a records request.

The bottom line

A death certificate is one of the richest single documents in genealogy and one of the easiest to over-trust. Read it as two documents: the medical half, filled out by a professional and generally reliable, and the demographic half, filled out from an informant’s memory and only as accurate as that person’s knowledge. Mine it for the parents’ names and the birth clues, then confirm those leads against records made closer to the events. Used that way, a death certificate is exactly what it should be, the doorway into the generation before, not the final word on it.
