Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Publix Super Markets, Inc. and subsidiaries (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Accordingly, the accompanying statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these statements include all adjustments that are of a normal and recurring nature necessary to present fairly the Company’s financial position and results of operations. Due to the seasonal nature of the Company’s business, the results of operations for the three and six months ended July 1, 2017 are not necessarily indicative of the results for the entire 2017 fiscal year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . 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 as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standard	(2) Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) requiring companies to change the methodology used to measure credit losses on financial instruments. The ASU is effective for reporting periods beginning after December 15, 2019 with early adoption permitted only for reporting periods beginning after December 15, 2018. The Company does not expect the adoption of the ASU to have a material effect on the Company’s financial condition or results of operations. The adoption of the ASU will have no effect on the Company’s cash flows. In February 2016, the FASB issued an ASU on lease accounting. The ASU requires the lease rights and obligations arising from lease contracts, including existing and new arrangements, to be recognized as assets and liabilities on the balance sheet. The ASU is effective for reporting periods beginning after December 15, 2018 with early adoption permitted. While the Company is still evaluating the ASU, the Company expects the adoption of the ASU to have a material effect on the Company’s financial condition due to the recognition of the lease rights and obligations as assets and liabilities on the consolidated balance sheets. The Company does not expect the adoption of the ASU to have a material effect on the Company’s results of operations. The adoption of the ASU will have no effect on the Company’s cash flows. In January 2016, the FASB issued an ASU requiring companies to measure equity securities at fair value with changes in fair value recognized in net earnings as opposed to other comprehensive earnings. The ASU is effective for reporting periods beginning after December 15, 2017. The adoption of the ASU will have an effect on the Company’s results of operations. The extent of the effect on results of operations will vary with the changes in the fair value of equity securities. The adoption of the ASU will have no effect on the Company’s financial condition or cash flows. In November 2015, the FASB issued an ASU requiring companies to classify deferred tax assets and liabilities in the noncurrent section of the balance sheet. The ASU is effective for reporting periods beginning after December 15, 2016. The Company retrospectively adopted the ASU during the quarter ended April 1, 2017, and therefore reclassified $77,496,000 from current deferred tax assets to noncurrent deferred tax liabilities as of December 31, 2016 on the condensed consolidated balance sheet. In May 2014, the FASB issued an ASU on the recognition of revenue from contracts with customers. The ASU requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The ASU is effective for reporting periods beginning after December 15, 2017. The Company does not expect the adoption of the ASU to have a material effect on the Company’s financial condition, results of operations or cash flows.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	(3) Fair Value of Financial Instruments The fair value of certain of the Company’s financial instruments, including cash and cash equivalents, trade receivables and accounts payable, approximates their respective carrying amounts due to their short-term maturity. The fair value of available-for-sale (AFS) securities is based on market prices using the following measurement categories: Level 1 – Fair value is determined by using quoted prices in active markets for identical investments. AFS securities that are included in this category are primarily mutual funds, exchange traded funds and equity securities. Level 2 – Fair value is determined by using other than quoted prices. By using observable inputs (for example, benchmark yields, interest rates, reported trades and broker dealer quotes), the fair value is determined through processes such as benchmark curves, benchmarking of like securities and matrix pricing of corporate, state and municipal bonds by using pricing of similar bonds based on coupons, ratings and maturities. AFS securities that are included in this category are primarily debt securities (tax exempt and taxable bonds). Level 3 – Fair value is determined by using other than observable inputs. Fair value is determined by using the best information available in the circumstances and requires significant management judgment or estimation. No AFS securities are currently included in this category. Following is a summary of fair value measurements for AFS securities as of July 1, 2017 and December 31, 2016 : Fair Value Level 1 Level 2 Level 3 (Amounts are in thousands) July 1, 2017 $ 6,990,877 1,886,875 5,104,002 — December 31, 2016 6,738,618 1,286,625 5,451,993 —

Investments, Debt and Equity Securities [Abstract]
Investments	(4) Investments Debt and equity securities are classified as AFS and are carried at fair value. The Company evaluates whether AFS securities are other-than-temporarily impaired (OTTI) based on criteria that include the extent to which cost exceeds market value, the duration of the market value decline, the credit rating of the issuer or security, the failure of the issuer to make scheduled principal or interest payments and the financial health and prospects of the issuer or security. Declines in the value of AFS securities determined to be OTTI are recognized in earnings and reported as OTTI losses. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the debt security or if the Company will be required to sell the debt security prior to any anticipated recovery. If the Company determines that a debt security is OTTI under these circumstances, the impairment recognized in earnings is measured as the difference between the amortized cost and the current fair value. A debt security is also determined to be OTTI if the Company does not expect to recover the amortized cost of the debt security. However, in this circumstance, if the Company does not intend to sell the debt security and will not be required to sell the debt security, the impairment recognized in earnings equals the estimated credit loss as measured by the difference between the present value of expected cash flows and the amortized cost of the debt security. Expected cash flows are discounted using the debt security’s effective interest rate. An equity security is determined to be OTTI if the Company does not expect to recover the cost of the equity security. Declines in the value of AFS securities determined to be temporary are reported net of income taxes as other comprehensive losses and included as a component of stockholders’ equity. Interest and dividend income, amortization of premiums, accretion of discounts and realized gains and losses on AFS securities are included in investment income. Interest income is accrued as earned. Dividend income is recognized as income on the ex-dividend date of the security. The cost of AFS securities sold is based on the first-in, first-out method. Following is a summary of AFS securities as of July 1, 2017 and December 31, 2016 : Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (Amounts are in thousands) July 1, 2017 Tax exempt bonds $ 2,677,257 5,775 5,249 2,677,783 Taxable bonds 2,438,718 3,163 17,501 2,424,380 Restricted investments 164,548 309 — 164,857 Equity securities 1,655,508 74,794 6,445 1,723,857 $ 6,936,031 84,041 29,195 6,990,877 December 31, 2016 Tax exempt bonds $ 3,036,060 2,211 24,649 3,013,622 Taxable bonds 2,469,192 1,359 33,903 2,436,648 Restricted investments 164,548 — 463 164,085 Equity securities 1,021,340 110,879 7,956 1,124,263 $ 6,691,140 114,449 66,971 6,738,618 Realized gains on sales of AFS securities totaled $64,014,000 and 98,636,000 for the three and six months ended July 1, 2017 , respectively.

The Company continues to receive scheduled principal and interest payments on these debt securities. Unrealized losses related to equity securities are primarily due to temporary equity market fluctuations that are expected to recover.

Consolidation Of Joint Ventures And Long Term Debt [Abstract]
Consolidation Of Joint Ventures And Long Term Debt Disclosure [Text Block]	(5) Consolidation of Joint Ventures and Long-Term Debt From time to time, the Company enters into Joint Ventures (JV), in the legal form of limited liability companies, with certain real estate developers to partner in the development of shopping centers with the Company as the anchor tenant. The Company consolidates certain of these JVs in which it has a controlling financial interest. The Company is considered to have a controlling financial interest in a JV when it has (1) the power to direct the activities of the JV that most significantly impact the JV’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from the JV that could potentially be significant to such JV. The Company evaluates a JV using specific criteria to determine whether the Company has a controlling financial interest and is the primary beneficiary of the JV. Factors considered in determining whether the Company is the primary beneficiary include risk and reward sharing, experience and financial condition of the other JV members, voting rights, involvement in routine capital and operating decisions and each member’s influence over the JV owned shopping center’s economic performance. Generally, most major JV decision making is shared between all members. In particular, the use and sale of JV assets, business plans and budgets are generally required to be approved by all members. However, the Company, through its anchor tenant operating lease agreement, has the power to direct the activities that most significantly influence the economic performance of the JV owned shopping center. Additionally, through its member equity interest in the JV, the Company will receive a significant portion of the JV’s benefits or is obligated to absorb a significant portion of the JV’s losses. As of July 1, 2017 , the carrying amounts of the assets and liabilities of the consolidated JVs were $140,105,000 and $63,074,000 , respectively. As of December 31, 2016 , the carrying amounts of the assets and liabilities of the consolidated JVs were $102,254,000 and $53,278,000 , respectively. The assets are owned by and the liabilities are obligations of the JVs, not the Company, except for a portion of the long-term debt of certain JVs guaranteed by the Company. The JVs are financed with capital contributions from the members, loans and/or the cash flows generated by the JV owned shopping centers once in operation. Total earnings attributable to noncontrolling interests for 2017 and 2016 were immaterial. The Company’s involvement with these JVs does not have a significant effect on the Company’s financial condition, results of operations or cash flows. The Company’s long-term debt results primarily from the consolidation of loans of certain JVs and loans assumed in connection with the acquisition of certain shopping centers with the Company as the anchor tenant. No loans were assumed during the six months ended July 1, 2017 . The Company assumed loans totaling $23,491,000 during the six months ended June 25, 2016 . Maturities of JV loans range from June 2020 through April 2027 and have variable interest rates based on a LIBOR index plus 175 to 250 basis points. Maturities of assumed shopping center loans range from September 2017 through January 2027 and have fixed interest rates ranging from 3.7% to 7.5% .

Retirement Benefits [Abstract]
Retirement Plan	(6) Retirement Plan The Company has a trusteed, noncontributory Employee Stock Ownership Plan (ESOP) for the benefit of eligible employees. Since the Company’s common stock is not traded on an established securities market, the ESOP includes a put option for shares of the Company’s common stock distributed from the ESOP. Shares are distributed from the ESOP primarily to separated vested participants and certain eligible participants who elect to diversify their account balances. Under the Company’s administration of the ESOP’s put option, if the owners of distributed shares desire to sell their shares, the Company is required to purchase the shares at fair value for a specified time period after distribution of the shares from the ESOP. The fair value of distributed shares subject to the put option totaled $433,940,000 and $425,514,000 as of July 1, 2017 and December 31, 2016 , respectively. The cost of the shares held by the ESOP totaled $2,828,279,000 and $2,642,583,000 as of July 1, 2017 and December 31, 2016 , respectively. Due to the Company’s obligation under the put option, the distributed shares subject to the put option and the shares held by the ESOP are classified as temporary equity in the mezzanine section of the condensed consolidated balance sheets and totaled $3,262,219,000 and $3,068,097,000 as of July 1, 2017 and December 31, 2016 , respectively. The fair value of the shares held by the ESOP totaled $7,952,835,000 and $8,356,659,000 as of July 1, 2017 and December 31, 2016 , respectively.

Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Publix Super Markets, Inc. and subsidiaries (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Accordingly, the accompanying statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these statements include all adjustments that are of a normal and recurring nature necessary to present fairly the Company’s financial position and results of operations. Due to the seasonal nature of the Company’s business, the results of operations for the three and six months ended July 1, 2017 are not necessarily indicative of the results for the entire 2017 fiscal year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . 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 as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standard	(2) Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) requiring companies to change the methodology used to measure credit losses on financial instruments. The ASU is effective for reporting periods beginning after December 15, 2019 with early adoption permitted only for reporting periods beginning after December 15, 2018. The Company does not expect the adoption of the ASU to have a material effect on the Company’s financial condition or results of operations. The adoption of the ASU will have no effect on the Company’s cash flows. In February 2016, the FASB issued an ASU on lease accounting. The ASU requires the lease rights and obligations arising from lease contracts, including existing and new arrangements, to be recognized as assets and liabilities on the balance sheet. The ASU is effective for reporting periods beginning after December 15, 2018 with early adoption permitted. While the Company is still evaluating the ASU, the Company expects the adoption of the ASU to have a material effect on the Company’s financial condition due to the recognition of the lease rights and obligations as assets and liabilities on the consolidated balance sheets. The Company does not expect the adoption of the ASU to have a material effect on the Company’s results of operations. The adoption of the ASU will have no effect on the Company’s cash flows. In January 2016, the FASB issued an ASU requiring companies to measure equity securities at fair value with changes in fair value recognized in net earnings as opposed to other comprehensive earnings. The ASU is effective for reporting periods beginning after December 15, 2017. The adoption of the ASU will have an effect on the Company’s results of operations. The extent of the effect on results of operations will vary with the changes in the fair value of equity securities. The adoption of the ASU will have no effect on the Company’s financial condition or cash flows. In November 2015, the FASB issued an ASU requiring companies to classify deferred tax assets and liabilities in the noncurrent section of the balance sheet. The ASU is effective for reporting periods beginning after December 15, 2016. The Company retrospectively adopted the ASU during the quarter ended April 1, 2017, and therefore reclassified $77,496,000 from current deferred tax assets to noncurrent deferred tax liabilities as of December 31, 2016 on the condensed consolidated balance sheet. In May 2014, the FASB issued an ASU on the recognition of revenue from contracts with customers. The ASU requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The ASU is effective for reporting periods beginning after December 15, 2017. The Company does not expect the adoption of the ASU to have a material effect on the Company’s financial condition, results of operations or cash flows.
