Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Publix Super Markets, Inc. and subsidiaries (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 June 30, 2018 are not necessarily indicative of the results for the entire 2018 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 30, 2017 . 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 requiring the lease rights and obligations arising from lease contracts, including existing and new arrangements, 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 approximately $3 billion of 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 equity securities be measured at fair value with net unrealized gains and losses from changes in the fair value recognized in earnings. The ASU is effective for reporting periods beginning after December 15, 2017. In 2018, the Company prospectively adopted the ASU and reclassified the cumulative effect of the net unrealized gain on equity securities net of income taxes as of December 31, 2017 of $198,310,000 from accumulated other comprehensive earnings to retained earnings. The effect of the ASU on results of operations will vary with changes in the fair value of equity securities. In May 2014, the FASB issued an ASU requiring additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The ASU is effective for reporting periods beginning after December 15, 2017. In 2018, the Company adopted the ASU on a modified retrospective basis. The adoption of the ASU did not 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 investments 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. Investments included in this category are equity securities (exchange traded funds and individual equity securities) and a restricted investment held as collateral (money market/mutual fund), collectively referred to as 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. Investments 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 investments are currently included in this category. Following is a summary of fair value measurements for investments as of June 30, 2018 and December 30, 2017 : Fair Value Level 1 Level 2 Level 3 (Amounts are in thousands) June 30, 2018 $ 6,628,889 2,774,860 3,854,029 — December 30, 2017 6,433,311 2,545,320 3,887,991 —

Investments, Debt and Equity Securities [Abstract]
Investments	(4) Investments (a) Debt Securities Debt securities are classified as available-for-sale and carried at fair value. The Company evaluates whether debt securities are other-than-temporarily impaired (OTTI) based on criteria that include the extent to which the cost (cost of the debt security adjusted for amortization of premium or accretion of discount) 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 fair value of debt 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 cost and the fair value. A debt security is also determined to be OTTI if the Company does not expect to recover the 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 cost of the debt security. Expected cash flows are discounted using the debt security’s effective interest rate. Changes in the fair value of debt securities determined to be temporary are reported in other comprehensive earnings net of income taxes and included as a component of stockholders’ equity. Following is a summary of debt securities as of June 30, 2018 and December 30, 2017 : Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (Amounts are in thousands) June 30, 2018 Tax exempt bonds $ 1,498,690 189 15,898 1,482,981 Taxable bonds 2,229,148 335 60,235 2,169,248 $ 3,727,838 524 76,133 3,652,229 December 30, 2017 Tax exempt bonds $ 1,811,523 602 16,420 1,795,705 Taxable bonds 2,115,174 695 25,443 2,090,426 $ 3,926,697 1,297 41,863 3,886,131 The cost and fair value of debt securities by expected maturity as of June 30, 2018 and December 30, 2017 are as follows: June 30, 2018 December 30, 2017 Cost Fair Value Cost Fair Value (Amounts are in thousands) Due in one year or less $ 667,148 665,338 917,576 915,579 Due after one year through five years 2,771,861 2,701,701 2,794,099 2,757,504 Due after five years through ten years 276,032 272,281 205,792 203,533 Due after ten years 12,797 12,909 9,230 9,515 $ 3,727,838 3,652,229 3,926,697 3,886,131 Following is a summary of temporarily impaired debt securities by the time period impaired as of June 30, 2018 and December 30, 2017 : Less Than 12 Months 12 Months or Longer Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses (Amounts are in thousands) June 30, 2018 Tax exempt bonds $ 1,335,920 13,364 122,314 2,534 1,458,234 15,898 Taxable bonds 1,158,976 22,465 938,835 37,770 2,097,811 60,235 $ 2,494,896 35,829 1,061,149 40,304 3,556,045 76,133 December 30, 2017 Tax exempt bonds $ 1,543,151 13,827 136,217 2,593 1,679,368 16,420 Taxable bonds 811,886 4,908 1,153,645 20,535 1,965,531 25,443 $ 2,355,037 18,735 1,289,862 23,128 3,644,899 41,863 There are 456 debt securities contributing to the total unrealized losses of $76,133,000 as of June 30, 2018 . Unrealized losses related to debt securities are primarily due to increases in interest rates impacting the market value of certain bonds. The Company continues to receive scheduled principal and interest payments on these debt securities. (b) Equity Securities In 2018, the Company adopted the ASU requiring equity securities be measured at fair value with net unrealized gains and losses from changes in the fair value recognized in earnings (fair value adjustment). The fair value adjustment also includes the cumulative effect of the ASU as of December 31, 2017 reclassified from accumulated other comprehensive earnings to retained earnings. Prior to adoption of the ASU, changes in the fair value of equity securities were accounted for similar to changes in the fair value of debt securities. Equity securities were classified as available-for-sale and carried at fair value. Declines in the fair value of equity securities determined to be OTTI were recognized in earnings and reported as OTTI losses. An equity security was determined to be OTTI if the Company did not expect to recover the cost of the equity security. Changes in the fair value of equity securities determined to be temporary were reported in other comprehensive earnings net of income taxes and included as a component of stockholders’ equity. Following is a summary of the fair value of equity securities as of June 30, 2018 and December 30, 2017 : June 30, 2018 December 30, 2017 (Amounts are in thousands) Equity securities $ 2,815,353 2,383,095 Restricted investment 161,307 164,085 $ 2,976,660 2,547,180 The Company maintains a restricted investment for the benefit of the Company’s insurance carrier related to self-insurance reserves. This investment is held as collateral and is not used for self-insured claims payments. (c) Investment Income Interest and dividend income, amortization of premiums, accretion of discounts and realized gains and losses on the sale of debt and equity securities are included in investment income. Interest income is accrued as earned. Dividend income is recognized as income on the ex-dividend date. The cost of debt and equity securities sold is based on the first-in, first-out method. With the adoption of the ASU, the fair value adjustment on equity securities held as of June 30, 2018 is also included in investment income. In the following table, net realized gain on the sale of investments represents the difference between the cost and the proceeds from the sale of debt and equity securities. For the three and six months ended June 30, 2018 , the net realized gain on the sale of investments excludes the net gain on the sale of equity securities previously recognized through the fair value adjustment, which is presented separately. Following is a summary of investment income for the three and six months ended June 30, 2018 and July 1, 2017 : Three Months Ended Six Months Ended June 30, 2018 July 1, 2017 June 30, 2018 July 1, 2017 (Amounts are in thousands) Interest income $ 19,762 20,908 38,256 42,047 Dividend income 11,299 9,529 21,897 17,870 Net realized gain on sale of investments 16,642 63,289 23,667 94,558 47,703 93,726 83,820 154,475 Fair value adjustment (net unrealized gain) on equity securities held at end of period 76,829 — 51,047 — Net gain on sale of equity securities previously recognized through fair value adjustment (16,217 ) — (22,414 ) — $ 108,315 93,726 112,453 154,475

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 June 30, 2018 , the carrying amounts of the assets and liabilities of the consolidated JVs were $147,486,000 and $75,228,000 , respectively. As of December 30, 2017 , the carrying amounts of the assets and liabilities of the consolidated JVs were $144,559,000 and $67,631,000 , 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 2018 and 2017 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. The Company assumed loans totaling $9,936,000 during the six months ended June 30, 2018 . No loans were assumed during the six months ended July 1, 2017 . 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 August 2018 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 $328,906,000 and $311,315,000 as of June 30, 2018 and December 30, 2017 , respectively. The cost of the shares held by the ESOP totaled $2,921,412,000 and $2,741,823,000 as of June 30, 2018 and December 30, 2017 , 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 $3,250,318,000 and $3,053,138,000 as of June 30, 2018 and December 30, 2017 , respectively. The fair value of the shares held by the ESOP totaled $8,095,277,000 and $7,252,657,000 as of June 30, 2018 and December 30, 2017 , 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 (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 June 30, 2018 are not necessarily indicative of the results for the entire 2018 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 30, 2017 . 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 requiring the lease rights and obligations arising from lease contracts, including existing and new arrangements, 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 approximately $3 billion of 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 equity securities be measured at fair value with net unrealized gains and losses from changes in the fair value recognized in earnings. The ASU is effective for reporting periods beginning after December 15, 2017. In 2018, the Company prospectively adopted the ASU and reclassified the cumulative effect of the net unrealized gain on equity securities net of income taxes as of December 31, 2017 of $198,310,000 from accumulated other comprehensive earnings to retained earnings. The effect of the ASU on results of operations will vary with changes in the fair value of equity securities. In May 2014, the FASB issued an ASU requiring additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The ASU is effective for reporting periods beginning after December 15, 2017. In 2018, the Company adopted the ASU on a modified retrospective basis. The adoption of the ASU did not have a material effect on the Company’s financial condition, results of operations or cash flows.
