Reference excerpt

This is a list of long marriages. It includes only marriages extending over at least 80 years.

Background A study by Robert and Jeanette Lauer, reported in the Journal of Family Issues, conducted on 40 sets of spouses married for at least 50 years, concluded that the long-term married couples received high scores on the Lock-Wallace marital satisfaction test and were closely aligned on how their marriages were doing. In a 1979 study on about 55 couples in marriages with an average length of 55.5 years, couples said their marriages lasted so long because of mutual devotion and special regard for each other. Couples who have been married for a long time have a lower likelihood of divorcing because "common economic interests and friendship networks increase over time" and enduring stress can assist in sustaining the relationship. Another study found that people in long marriages are wedded to the idea of "marital permanency" in which "They don't see divorce as an option". Sociologist Pepper Schwartz, the American Association of Retired Persons's relationships authority, said that it was helpful to have a spouse who is quick to recover when there are surprises in life. A study of 1,152 couples who had been married for over 50 years found that they attributed their long marriages to faith in each other, love, ability to make concessions, admiration for each other, reliance on each other, children, and strong communication. Bowling Green State University (BGSU)'s National Center for Family and Marriage Research found that 7% of American marriages last at least 50 years.

Recording longest marriages The longest marriage recorded (although not officially recognized) is a granite wedding anniversary (90 years) between Karam and Kartari Chand, who both lived in the United Kingdom, but were married in India. The couple married in 1925, and died in 2016 and 2019, respectively. Guinness World Records published its first edition in 1955. In the 1984 to 1998 editions, the longest recorded marriages were between Sir Temulji Bhicaji and Lady Nariman, and Lazarus and Mary Molly Rowe. According to the New England Historical and Genealogical Register, both of them are stated as spanning 86 years. Guinness has since recognized couples with longer marriage spans, with the current world record holders (as of 2024) being David and Sarah Hiller. It also keeps record of the oldest married couple by aggregate age. Other organizations have created events where they honor couples with long marriages. In 2011, World Marriage Encounter (WME), an American organization that was responsible for making a World Marriage Day, created a Longest Married Couple Project (LMCP), where they pick a couple with a long marriage and honor them on Valentine's Day. They have since expanded the awards to representatives in each of the 50 states, although the candidates selected are not necessarily the ones with record-setting marriages. Starting in 2004, the Louisiana Family Forum (LFF) has honored its annual list of long-time married couples in that particular state, beginning with George and Germaine Briant.

Worked examples

Example 1 — a first encounter with List of long marriages

Start with the simplest possible case. Write down what List of long marriages claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of long marriages before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of long marriages ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of long marriages

In research: List of long marriages appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of long marriages in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of long marriages is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of longest-duration things, Lists of people-related superlatives, Lists of people by marital status, so understanding it makes those chapters shorter.
In everyday life: Look for List of long marriages outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
