Definition
Statistical life expectancy and annuity tables compiled from mortality data gathered in Carlisle, England, in the late eighteenth century. The tables record the probability of survival at each age across a given population, enabling calculation of life expectancies and the present value of annuities, life estates, and similar interests that depend on how long a person is expected to live. Courts and practitioners historically used the Carlisle Tables as a standard actuarial reference when damages, settlements, or valuations required an estimate of a person's remaining years of life.
Why It Matters in Research
The Carlisle Tables matter primarily in historical legal research, not in contemporary practice. Through much of the nineteenth century and into the early twentieth, they were the tables courts reached for when calculating damages for wrongful death, personal injury, loss of earning capacity, or the value of a life estate. A researcher reading older opinions or treatises that reference "life tables," "annuity tables," or "the Carlisle tables" should understand that these terms point to this specific dataset, not to modern actuarial instruments.
Two traps exist for the unwary. First, the tables were eventually superseded by more accurate mortality data — the American Experience Table, and later the standard actuarial tables issued by government and insurance industry bodies. A case relying on the Carlisle Tables may reflect mortality assumptions that no longer reflect accepted practice and were already considered outdated by many courts by the late nineteenth century. Second, researchers should not confuse a court's use of "life tables" generically with an endorsement of the Carlisle data specifically; courts sometimes used the phrase interchangeably, and identifying which tables were actually applied requires reading the underlying record or expert testimony.
For damages research, the Carlisle Tables sit at an intersection of tort law, evidence, and actuarial practice. Historical sources discussing the admissibility of life tables as evidence — a contested question in many jurisdictions through the nineteenth century — frequently use the Carlisle Tables as the exemplar.
Historical Dictionary Support
The historical dictionaries agree on substance but disagree on one factual detail: the date of compilation. Black's Law Dictionary (both the first and second editions) places compilation "about 1780," which aligns with the work of Dr. John Heysham, whose Carlisle Bills of Mortality data were compiled in the 1770s and 1780s and later reduced to actuarial table form by Joshua Milne in 1815. Bouvier's Law Dictionary gives "about 1870" — almost certainly a typographical or editorial error, as no recognized compilation of Carlisle Tables occurred near that date. Researchers relying on Bouvier for the date of this source should treat that figure with caution.
Anderson's Dictionary of Law cross-references its own entry for TABLE rather than offering an independent definition, which provides no additional analytical content.
None of the historical dictionaries address the tables' declining authority or their displacement by later actuarial data — a silence that could mislead a researcher into treating the Carlisle Tables as more current or authoritative than they were by the time many reported cases were decided.
Jurisdictional Note
American courts varied in their willingness to admit life tables as evidence and in which tables they endorsed. Some jurisdictions preferred locally compiled or government-issued tables over the Carlisle data. English courts, for whom the Carlisle Tables were domestic in origin, treated them with greater routine acceptance. Researchers should check jurisdiction-specific rules on the admissibility of actuarial evidence when working with historical damages cases.
