Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying 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 consolidated financial position at June 30, 2022, and the consolidated results of operations, comprehensive income, and cash flows for the periods ended June 30, 2022 and 2021. The interim period 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 24, 2022.
Use of Estimates	Use of Estimates: The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See further documentation in the significant accounting policies or the accompanying notes.
