Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	Note 2—New Accounting Standards Accounting Pronouncements Adopted in the Current Year Standard Description Effective Date Effect on the Consolidated Financial Statements ASU No. 2020-08 , Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs The standard was issued as an amendment to ASU 2017-08, and clarifies that callable debt securities with a premium should be amortized to the next call date. This standard became effective on January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. Accounting Pronouncements Yet to be Adopted Standard Description Effective Date Effect on the Consolidated Financial Statements ASU No. 2018-12/2019-09/2020-11 , Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, with clarification guidance issued in November 2019 and 2020. ASU 2018-12 is a significant change to our current accounting and disclosure of long-duration contracts, which is our primary business. The guidance was primarily issued to: 1) improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows, 2) simplify and improve the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts, 3) simplify the amortization of deferred acquisition costs, and 4) improve the effectiveness of the required disclosures. As a result of the issuance of ASU 2020-11 in November 2020, the effective date for this standard was changed to January 1, 2023. Early adoption is available. The Company is currently in the process of evaluating the impact this standard will have on the consolidated financial statements and disclosures, specifically assessing key accounting policies, assumption and data inputs, controls, and enhanced system solutions. As of the balance sheet date, the Company is continuing to upgrade its valuation systems as part of its implementation plan. In addition, significant progress has been made allowing the Company to execute parallel valuation runs on major blocks of business and is updating its accounting policies. Due to the overall nature of the standard, the impact on the consolidated financial statements is expected to be significant. At this time, the Company does not have an estimate of the impact. The Company does not expect to early adopt this ASU and has selected a modified retrospective transition method.

The weighted-average quality rating of all unrealized loss positions at amortized cost was BBB+ and BBB- as of June 30, 2021 and December 31, 2020, respectively. The following table discloses unrealized investment losses by class and major sector of fixed maturities available for sale for which an allowance for credit losses has not been recorded at June 30, 2021. Gross unrealized losses may fluctuate quarter over quarter due to adverse factors in the market that affect our holdings, such as changes in interest rates or credit spreads. The Company considers many factors when determining whether an allowance for a credit loss should be recorded. While the Company holds securities that may be in an unrealized loss position from time to time, Globe Life does not intend to sell and it is likely that management will not be required to sell the fixed maturities prior to their anticipated recovery or maturity due to the strong cash flows generated by its insurance operations.

For each investment, the Company has elected the fair value option, but would have been otherwise accounted for as an equity method investment. The fair value option is assessed for each individual investment and concluded at the inception of the investment. Additionally, each investment is evaluated under ASC 810, Consolidation to determine if it is a variable interest entity and would qualify for consolidation; none of the investments qualify for consolidation as the Company is not the primary beneficiary in any of these investments. The investments are reported at the Company's pro-rata share of the investment fund's net asset value or its equivalent (NAV) as a practical expedient for fair value. Changes in the net asset value are recorded in "Realized gains (losses)" on the Condensed Consolidated Statements of Operations . Distributions received from the funds arise from income generated by the underlying investments as well as the liquidation of the underlying investments. Periodic distributions are recorded in net investment income until cumulative distributions exceed our pro-rata share of operating earnings at which point the distributions will reduce the carrying value. Our maximum exposure to loss is equal to the outstanding carrying value and future funding commitments. During the quarter, the Company committed to one new limited partnership. The Company had $72 million of capital called during the quarter from existing investment funds, reducing our unfunded commitments. Our unfunded commitments were $409 million as of June 30, 2021.

Loans are rated low, moderate, and high. The risk categories consider many different factors such as quality of asset, borrower status, as well as macroeconomic factors including COVID-19. These loans, originated in 2017 to 2021, are transitional or under construction and may not yet be income producing. Certain ratios, such as loan to value and debt service coverage ratios, may not be evaluated as the value of the underlying transitional property significantly fluctuates based on completion of the project.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 5—Commitments and Contingencies Guarantees : The Parent Company has guaranteed letters of credit in connection with its credit facility with a group of banks. The letters of credit were issued by TMK Re, Ltd., a wholly-owned subsidiary, to secure TMK Re, Ltd.’s obligation for claims on certain policies reinsured by TMK Re, Ltd. that were sold by other Globe Life insurance subsidiaries. These letters of credit facilitate TMK Re, Ltd.’s ability to reinsure the business of Globe Life's insurance carriers. The agreement expires in 2023. The maximum amount of letters of credit available is $250 million. The Parent Company would be liable to the extent that TMK Re, Ltd. does not pay the reinsured party. As of June 30, 2021 and December 31, 2020, the outstanding balance was $135 million. Litigation : Globe Life Inc. (formerly Torchmark Corporation) and its subsidiaries, in common with the insurance industry in general, are subject to litigation, including putative class action litigation, alleged breaches of contract, torts, including bad faith and fraud claims based on alleged wrongful or fraudulent acts of agents of the Parent Company's insurance subsidiaries, employment discrimination, and miscellaneous other causes of action. Based upon information presently available, and in light of legal and other factual defenses available to the Parent Company and its subsidiaries, management does not believe that it is reasonably possible that such litigation will have a material adverse effect on Globe Life's financial condition, future operating results or liquidity; however, assessing the eventual outcome of litigation necessarily involves forward-looking speculation as to judgments to be made by judges, juries and appellate courts in the future. This bespeaks caution, particularly in states with reputations for high punitive damage verdicts. Globe Life's management recognizes that large punitive damage awards bearing little or no relation to actual damages continue to be awarded by juries in jurisdictions in which the Company has substantial business, creating the potential for unpredictable material adverse judgments in any given punitive damage suit. On January 4, 2021, putative class and collective action litigation was filed against National Income Life Insurance Company in the United States District Court for the Northern District of New York. (John Turner v. National Income Life Insurance Company, Case No. 5:21-cv-0003). Plaintiff Turner is a former New York National Income agent who asserted a claim under New York law on behalf of a putative New York class of trainees and sales agents for the six years prior to February 13, 2020 through case conclusion. He made a claim under the New York Labor Law for alleged failure to pay minimum wage and overtime, and for expense reimbursement. In addition, Mr. Turner asserted a claim under the Fair Labor Standards Act (FLSA) on behalf of trainees and sales agents for the three years prior to February 13, 2020 through case conclusion. The FLSA claim alleged failure to pay for all hours worked and sought expense reimbursement. The lawsuit also requested declaratory relief and liquidated damages. Prior to filing a motion to compel arbitration of Mr. Turner’s individual claims, National Income reached a settlement with Mr. Turner for a non-material sum as to his individual claims, and the litigation has been dismissed.

Business Segments	Jun. 30, 2021
Segment Reporting [Abstract]
Business Segments	Note 10—Business Segments Globe Life is organized into four segments: life insurance, supplemental health insurance, annuities, and investments. In addition, other expenses not included in these segments are reported in "Corporate & Other." Globe Life's reportable insurance segments are based on the insurance product lines it markets and administers: life insurance, supplemental health insurance, and annuities. These major product lines are set out as reportable segments because of the common characteristics of products within these categories, comparability of margins, and the similarity in regulatory environment and management techniques. There is also an investment segment which manages the investment portfolio, debt, and cash flow for the insurance segments and the corporate function. The Company's chief operating decision makers evaluate the overall performance of the operations of the Company in accordance with these segments. Life insurance products marketed by Globe Life include traditional whole life and term life insurance. Health insurance products are generally guaranteed-renewable and include Medicare Supplement, critical illness, accident, and limited-benefit supplemental hospital and surgical coverage. Annuities include fixed-benefit contracts. Globe Life markets its insurance products through a number of distribution channels, each of which sells the products of one or more of Globe Life's insurance segments. Our distribution channels consist of the following exclusive agencies: American Income Life Division (American Income), Liberty National Division (Liberty National) and Family Heritage Division (Family Heritage); an independent agency, United American Division (United American); and our Direct to Consumer Division (Direct to Consumer). The tables below present segment premium revenue by each of Globe Life's distribution channels.

Substantially all of Globe Life's business is conducted in the United States. The measure of profitability established by the chief operating decision makers for the insurance segments is underwriting margin before other income and administrative expenses, in accordance with the manner in which the segments are managed. It essentially represents gross profit margin on insurance products before insurance administrative expenses and consists primarily of premium less net policy benefits, acquisition expenses, and commissions. Required interest on net policy liabilities (benefit reserves less deferred acquisition costs) is reflected as a component of the Investment segment (rather than as a component of underwriting margin in the insurance and annuity segments) in order to match this cost with the investment income earned on the assets supporting the net policy liabilities. The measure of profitability for the Investment segment is excess investment income, representing the income earned on the investment portfolio in excess of net policy requirements and financing costs associated with Globe Life's debt. Other than the above-mentioned interest allocations, no other intersegment revenues or expenses are recognized. Expenses directly attributable to corporate operations are included in the “Corporate & Other” category. Stock-based compensation expense is considered a corporate expense by Globe Life management and is included in this category. All other unallocated revenues and expenses on a pretax basis, including insurance administrative expense, are also included in the “Corporate & Other” segment category. Globe Life holds a sizable investment portfolio to support its insurance liabilities, the yield from which is used to offset policy benefit, acquisition, administrative and tax expenses. This yield or investment income is taken into account when establishing premium rates and profitability expectations for its insurance products. From time to time, investments are sold or called, or experience a credit loss event, each of which is reflected by the Company as realized gain (loss)—investments. These gains or losses generally occur as a result of disposition due to issuer calls, compliance with Company investment policies, or other reasons often beyond management’s control. Unlike investment income, realized gains and losses are incidental to insurance operations, and only overall yields are considered when setting premium rates or insurance product profitability expectations. While these gains and losses are not relevant to segment profitability or core operating results, they can have a material positive or negative result on net income. For these reasons, management removes realized investment gains and losses when it views its segment operations. Management removes items that are related to prior periods when evaluating the operating results of current periods. Management also removes non-operating items unrelated to the Company's core insurance activities when evaluating those results. Therefore, these items are excluded in its presentation of segment results, because accounting guidance requires that operating segment results be presented as management views its business. With the exception of the administrative settlements noted in the paragraphs above, all of these items are included in “Other operating expense” in the Condensed Consolidated Statements of Operations for the appropriate year. See additional detail below in the tables. The following tables set forth a reconciliation of Globe Life's revenues and operations by segment to its major income statement line items. See Note—1 Significant Accounting Policies for additional information concerning reconciling items of segment profits to pretax income.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying condensed consolidated financial statements of Globe Life have been prepared in accordance with the instructions to Form 10-Q. Therefore, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America (GAAP) for annual financial statements. However, in the opinion of management, these statements include all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial position at June 30, 2021, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended June 30, 2021 and 2020. The interim period condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements that are included in the Form 10-K filed with the Securities Exchange Commission (SEC) on February 25, 2021.
New Accounting Pronouncements	Accounting Pronouncements Adopted in the Current Year Standard Description Effective Date Effect on the Consolidated Financial Statements ASU No. 2020-08 , Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs The standard was issued as an amendment to ASU 2017-08, and clarifies that callable debt securities with a premium should be amortized to the next call date. This standard became effective on January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. Accounting Pronouncements Yet to be Adopted Standard Description Effective Date Effect on the Consolidated Financial Statements ASU No. 2018-12/2019-09/2020-11 , Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, with clarification guidance issued in November 2019 and 2020. ASU 2018-12 is a significant change to our current accounting and disclosure of long-duration contracts, which is our primary business. The guidance was primarily issued to: 1) improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows, 2) simplify and improve the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts, 3) simplify the amortization of deferred acquisition costs, and 4) improve the effectiveness of the required disclosures. As a result of the issuance of ASU 2020-11 in November 2020, the effective date for this standard was changed to January 1, 2023. Early adoption is available. The Company is currently in the process of evaluating the impact this standard will have on the consolidated financial statements and disclosures, specifically assessing key accounting policies, assumption and data inputs, controls, and enhanced system solutions. As of the balance sheet date, the Company is continuing to upgrade its valuation systems as part of its implementation plan. In addition, significant progress has been made allowing the Company to execute parallel valuation runs on major blocks of business and is updating its accounting policies. Due to the overall nature of the standard, the impact on the consolidated financial statements is expected to be significant. At this time, the Company does not have an estimate of the impact. The Company does not expect to early adopt this ASU and has selected a modified retrospective transition method.

While the Company holds securities that may be in an unrealized loss position from time to time, Globe Life does not intend to sell and it is likely that management will not be required to sell the fixed maturities prior to their anticipated recovery or maturity due to the strong cash flows generated by its insurance operations.
