Interim Consolidated Financial Statements	'
	Note 1 — Interim Consolidated Financial Statements
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related notes that appear in the Forrester Research, Inc. (“Forrester”) Annual Report on Form 10-K for the year ended December 31, 2013. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations, of comprehensive income and of cash flows as of the dates and for the periods presented have been included. The results of operations for the three and nine months ended September 30, 2014 may not be indicative of the results for the year ending December 31, 2014, or any other period.
	During the quarter ended March 31, 2014, the Company recorded $0.5 million of expenses for out-of-period corrections, of which $0.4 million related to depreciation and $0.1 million related to other immaterial amounts that related to prior periods. The Company has concluded that these errors are immaterial to all prior period financial statements.
	Fair Value Measurements
	The carrying amounts reflected in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate fair value due to their short-term maturities. See Note 3 – Marketable Investments for the fair value of the Company’s marketable investments.
	Revision of quarterly financial statements
	During the quarter ended December 31, 2013, the Company identified an immaterial prior period error of $0.1 million that had the effect of decreasing income tax expense for the three and nine months ended September 30, 2013. The Company has reflected in the financial information included in this Note the correction of this error in the period in which it originated (in thousands except per share amounts).

	The Company measures certain financial assets at fair value on a recurring basis, including cash equivalents and available-for-sale securities. The fair values of these financial assets have been classified as Level 1, 2 or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements.
	Level 1 — Fair value based on quoted prices in active markets for identical assets or liabilities.
	Level 2 — Fair value based on inputs other than Level 1 inputs that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 — Fair value based on unobservable inputs that are supported by little or no market activity and such inputs are significant to the fair value of the assets or liabilities.
	The following table represents the Company’s fair value hierarchy for its financial assets (cash equivalents and investments) measured at fair value on a recurring basis as of September 30, 2014 and December 31, 2013 (in thousands):

	Level 2 assets consist of the Company’s entire portfolio of federal, state, municipal and corporate bonds. Level 2 assets have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, typically utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation methods, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events.

Non-Marketable Investments	'
	Note 4 — Non-Marketable Investments
	At September 30, 2014 and December 31, 2013, the carrying value of the Company’s non-marketable investments, which were composed primarily of interests in technology-related private equity funds, was $4.1 million and $5.7 million, respectively, and is included in other assets in the Consolidated Balance Sheets.
	One of the Company’s investments, with a book value of $0.8 million and $0.9 million at September 30, 2014 and December 31, 2013, respectively, is being accounted for using the cost method and, accordingly, is valued at cost unless an other-than-temporary impairment in its value occurs. The other investments are being accounted for using the equity method as the investments are limited partnerships and the Company has an ownership interest in excess of 5% and, accordingly, the Company records its share of the investee’s operating results each period. Gains and losses from non-marketable investments were insignificant during the three and nine months ended September 30, 2014 and 2013, and are included in gains (losses) on investments, net in the Consolidated Statements of Income. During the nine months ended September 30, 2014 and 2013, gross distributions of $1.5 million and $0.3 million, respectively, were received from the funds.

	In the first quarter of 2014 the Company terminated approximately 1% of its employees across various geographies and functions primarily to realign resources due to the Company’s new organizational structure implemented in late 2013. The Company incurred $1.8 million of severance and related costs in the nine months ended September 30, 2014 related to this action. The costs under this plan are expected to be substantially paid by the end of 2014.
	During 2013 the Company incurred $1.9 million of severance and related costs for the elimination of 31 jobs or approximately 2.5% of its workforce worldwide in an effort to streamline its operations.

Earnings Per Share [Abstract]	'
Net Income Per Common Share	'
	Note 6 — Net Income Per Common Share
	Basic net income per common share is computed by dividing net income by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the diluted weighted average number of common shares and common equivalent shares outstanding during the period. The weighted average number of common equivalent shares outstanding has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable on the exercise of outstanding options and vesting of restricted stock units when dilutive.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Note 8 — Income Taxes
	Forrester provides for income taxes on an interim basis according to management’s estimate of the effective tax rate expected to be applicable for the full fiscal year. Certain items such as changes in tax rates and tax benefits related to disqualifying dispositions of incentive stock options are treated as discrete items and are recorded in the period in which they arise.
	Income tax expense for the nine months ended September 30, 2014 was $5.0 million resulting in an effective tax rate of 40.7% for the period. Income tax expense for the nine months ended September 30, 2013 was $7.0 million resulting in an effective tax rate of 39.1% for the period. The increase in the effective tax rate during the nine months ended September 30, 2014 as compared to the prior year was primarily due to the recognition of $0.2 million in the nine months ended September 30, 2014 for potential additional tax expense resulting from an on-going U.S. state audit.

Segment Reporting [Abstract]	'
Operating Segments	'
	Note 9 — Operating Segments
	At the end of 2013 the Company reorganized its fulfillment organization into a single global research organization and a single global product organization to better support its client base by facilitating better research collaboration and quality, promoting a more uniform client experience and improved customer satisfaction, and encouraging innovation. During 2013 the Company also established a dedicated consulting organization to provide research-based project consulting services to its clients, allowing the Company’s research personnel to spend additional time on writing research and providing shorter-term advisory services. As of January 1, 2014 the Company conformed its internal reporting to match the new organizational structure and as such is reporting segment information for the newly formed Research, Product and Project Consulting organizations. The 2013 segment amounts have been reclassified to conform to the current presentation.
	The Research segment includes the costs of the Company’s research personnel who are responsible for writing the research and performing the webinars and inquiries for the Company’s RoleView product. In addition, the research personnel deliver advisory services (such as workshops, speeches and advisory days) and a portion of the Company’s project consulting services. Revenue in this segment includes only revenue from advisory services and project consulting services that are delivered by the research personnel in this segment. During 2013, the Company began to transition the delivery of project consulting to a dedicated project consulting organization. The Company anticipates that the transition will be complete by the end of 2014 such that essentially all project consulting will be delivered by the project consulting organization in 2015.
	The Product segment includes the costs of the product management organization that is responsible for pricing, packaging and the launch of new products. In addition, this segment includes the costs of the Company’s data, Forrester Leadership Boards and events organizations. Revenue in this segment includes all revenue for the Company (including RoleView) except for revenue from advisory services and project consulting services that are delivered by personnel in the Research and Project Consulting segments.
	The Project Consulting segment includes the costs of the consultants that deliver the Company’s project consulting services. During 2013 the Company began to hire dedicated consultants to transition the delivery of project consulting services from research personnel (included in the Research segment) to the new Project Consulting segment. Revenue in this segment includes the project consulting revenue delivered by the consultants in this segment.
	The Company evaluates reportable segment performance and allocates resources based on segment revenues and expenses. Segment expenses include the direct expenses of each segment organization and exclude selling and marketing expenses, general and administrative expenses, stock-based compensation expense, depreciation expense, adjustments to incentive bonus compensation from target amounts, amortization of intangible assets, reorganization costs, other income and gains (losses) on investments. The accounting policies used by the segments are the same as those used in the consolidated financial statements.

	Note 10 — Recent Accounting Pronouncements
	In May, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. For Forrester, the standard will be effective in the first quarter of 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company has not yet selected a transition method. The Company is currently evaluating the potential changes from this ASU to its future financial reporting and disclosures.
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The standard addresses the balance sheet presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The standard requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this ASU as of January 1, 2014 did not have a material effect on the Company’s financial position.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related notes that appear in the Forrester Research, Inc. (“Forrester”) Annual Report on Form 10-K for the year ended December 31, 2013. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations, of comprehensive income and of cash flows as of the dates and for the periods presented have been included. The results of operations for the three and nine months ended September 30, 2014 may not be indicative of the results for the year ending December 31, 2014, or any other period.
	During the quarter ended March 31, 2014, the Company recorded $0.5 million of expenses for out-of-period corrections, of which $0.4 million related to depreciation and $0.1 million related to other immaterial amounts that related to prior periods.
Fair Value Measurements	'
