Basis of Presentation (Policies)	6 Months Ended
Jun. 30, 2021
Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated by the United States Securities and Exchange Commission (the "SEC"). Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Due to the impact of weather activity and the continued economic uncertainty resulting from the COVID-19 pandemic, the Company's operating results for the three and six months ended June 30, 2021 and financial position as of June 30, 2021 are not necessarily indicative of the results or financial position that may be expected for the year ending December 31, 2021 or for other future periods. The financial results from the Company's operations outside of the U.S., Canada, the Caribbean, and certain subsidiaries in the Philippines, are reported and consolidated on a two-month delayed basis (fiscal year-end of October 31) as permitted by GAAP in order to provide sufficient time for accumulation of their results.
Use of Estimates	The preparation of 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 assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. In the opinion of management, all adjustments (consisting only of normal recurring accruals and adjustments) considered necessary for a fair presentation have been included. There have been no material changes to our significant accounting policies and estimates from those disclosed in the Company's financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020 other than as disclosed herein.
Reclassification	Subsequent to December 31, 2020, the Company has reorganized its global service line structure to consist of Crawford Loss Adjusting, Crawford TPA Solutions, and Crawford Platform Solutions. Certain prior period amounts among the Company’s reportable segments have been reclassified to conform to the current presentation. These reclassifications had no effect on the Company's reported consolidated results. Significant intercompany transactions have been eliminated in consolidation.
Consolidation, Variable Interest Entity, Policy	The Company consolidates the liabilities of its deferred compensation plan and the related assets, which are held in a rabbi trust and also considered a variable interest entity ("VIE") of the Company. The rabbi trust was created to fund the liabilities of the Company's deferred compensation plan. The Company is considered the primary beneficiary of the rabbi trust because the Company directs the activities of the trust and can use the assets of the trust to satisfy the liabilities of the Company's deferred compensation plan.
Consolidation Noncontrolling Interests	Noncontrolling interests represent the minority shareholders' share of the net income or loss and shareholders' investment in consolidated subsidiaries. Noncontrolling interests are presented as a component of shareholders' investment in the unaudited Condensed Consolidated Balance Sheets and reflect the initial fair value of these investments by noncontrolling shareholders, along with their proportionate share of the income or loss of the subsidiaries, less any dividends or distributions.
CARES Act of 2020	On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The Company took advantage of certain aspects of the CARES Act such as the deferral of payroll tax deposits, which deferred the payment of 2020 payroll tax withholdings in the U.S., totaling $12,961,000, to be paid in equal installments at the end of 2021 and 2022.
Canada Emergency Wage Subsidy Program of 2020	The Canadian government enacted the Canada Emergency Wage Subsidy (“CEWS”) in 2020 to provide a wage subsidy to employers that suffered reductions in revenue resulting from the COVID-19 pandemic. The Company met the eligibility criteria to receive the wage subsidy in the first and second quarters of 2021, as well as the second, third and fourth quarters of 2020. The wage subsidy is included in "Costs of services provided, before reimbursements” or “Selling, general, and administrative expenses” on the Company's unaudited Condensed Consolidated Statements of Operations, depending on the location of the employees, and is recorded as a reduction of compensation expense. The Company recognized $2,195,000 and $4,072,000 as a reduction of compensation expense for the three and six months ended June 30, 2021, respectively, and $4,345,000 for the three and six months ended June 30, 2020. The Company will continue to evaluate the impact of government subsidies each period but does not expect to qualify for this subsidy in future quarters.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Adoption of New Accounting Standards Compensation-Retirement Benefits: Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20)." This update modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This update removes certain disclosure requirements including, but not limited to, the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and the amount and timing of plan assets expected to be returned to the employer. This update requires the disclosure of the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. This update also clarifies requirements for entities that provide aggregate disclosures for two or more plans. The update is effective for annual periods beginning after December 15, 2020, and interim periods thereafter. Early adoption is permitted. The Company adopted this guidance on January 1, 2021 with no material impact on its disclosures related to its retirement plans. Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 amends ASC 740 to simplify the accounting for income taxes by removing certain exceptions for foreign equity investments, intraperiod allocations and interim calculations, and adding guidance to reduce complexity in the accounting standard under the FASB’s simplification initiative. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. Upon adoption, the amendments in ASU 2019-12 should be applied on a prospective basis to all periods presented. The Company adopted this guidance on January 1, 2021 with no material impact on its results of operation, financial condition and cash flows. Pending Adoption of Recently Issued Accounting Standards There were no recently issued accounting standards that will have an impact to the Company.
Earnings per Share	The Company computes earnings per share of its non-voting Class A Common Stock ("CRD-A") and voting Class B Common Stock ("CRD-B") using the two-class method, which allocates the undistributed earnings in each period to each class on a proportionate basis. The Company's Board of Directors has the right, but not the obligation, to declare higher dividends on the CRD-A shares than on the CRD-B shares, subject to certain limitations. In periods when the dividend is the same for CRD-A and CRD-B or when no dividends are declared or paid to either class, the two-class method generally will yield the same earnings per share for CRD-A and CRD-B. Since the second quarter of 2020, the Board of Directors has declared the same dividend on CRD-A and CRD-B.
