Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The Company is a leading provider of analytics and insights that facilitate revenue growth, patient, employee and customer retention and patient engagement for healthcare providers, payers and other healthcare organizations in the United States and Canada. During the quarter ended September 30, 2014, the Company enlarged its operating segments from two to three to reflect a change in corporate reporting structure to the Company’s, Chief Executive Officer. The Company’s three operating segments are aggregated into one reporting segment because they have similar economic characteristics and meet the other aggregation criteria from the Financial Accounting Standards Board (“FASB”) guidance on segment disclosure. The three operating segments are National Research Corporation (United States), National Research Corporation Canada and Customer-Connect LLC (“Connect”), each of which offer a portfolio of solutions to address specific market needs around growth, retention, engagement and thought leadership for healthcare organizations. The condensed consolidated balance sheet of the Company at December 31, 2013, was derived from the Company’s audited consolidated balance sheet as of that date. All other financial statements contained herein are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) the Company considers necessary for a fair presentation of financial position, results of operations and cash flows in accordance with accounting principles generally accepted in the United States. Certain reclassifications have been made to the 2013 financial statement information to conform to the 2014 financial statement presentation. There was no impact on the previously reported net income and earnings per share information. Information and footnote disclosures included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto that are included in the Company’s Form 10-K for the year ended December 31, 2013, filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2014. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, National Research Corporation Canada, and the accounts of a variable interest entity, Connect, for which NRC has been deemed the primary beneficiary. All significant intercompany transactions and balances have been eliminated. The functional currency of the Company’s foreign subsidiary, National Research Corporation Canada, is the subsidiary’s local currency. The Company translates the assets and liabilities of its foreign subsidiary at the period-end rate of exchange and its foreign subsidiary’s income statement balances at the average rate prevailing during the period. The Company records the resulting translation adjustment in accumulated other comprehensive income, a component of shareholders’ equity. Since the undistributed earnings of the Company’s foreign subsidiary are considered to be indefinitely reinvested, no taxes were provided for on currency translation adjustments arising from converting the investment denominated in a foreign currency to U.S. dollars. Gains and losses related to transactions denominated in a currency other than the subsidiary’s local currency and short-term intercompany accounts are included in other income (expense) in the condensed consolidated statements of income.
Recapitalization [Policy Text Block]	In May 2013, the Company consummated a recapitalization (the “May 2013 Recapitalization”) pursuant to which the Company established two classes of common stock (class A common stock and class B common stock), issued a dividend of three shares of class A common stock for each share of the Company’s then existing common stock and reclassified each then existing share of common stock as 0.5 of one share of class B common stock.

The Company is a leading provider of analytics and insights that facilitate revenue growth, patient, employee and customer retention and patient engagement for healthcare providers, payers and other healthcare organizations in the United States and Canada.

During the quarter ended September 30, 2014, the Company enlarged its operating segments from two to three to reflect a change in corporate reporting structure to the Company’s, Chief Executive Officer. The Company’s three operating segments are aggregated into one reporting segment because they have similar economic characteristics and meet the other aggregation criteria from the Financial Accounting Standards Board (“FASB”) guidance on segment disclosure. The three operating segments are National Research Corporation (United States), National Research Corporation Canada and Customer-Connect LLC (“Connect”), each of which offer a portfolio of solutions to address specific market needs around growth, retention, engagement and thought leadership for healthcare organizations.
