米国では毎日3,010万人以上の児童生徒がNational School Lunch Programを通じて栄養の補給を受けており、9つの州が在籍する全生徒を対象とした恒久的な完全無償給食を保障しています。各州が無償化モデルを拡充する一方、各教育学区は食材価格の高騰、連邦補助金の算定基準、未払い給食費への対応に追われています。以下の数値は、USDA Food and Nutrition Service（FNS）、Food Research & Action Center（FRAC）、School Nutrition Association（SNA）、およびCDCの公式データに基づいています。
学校給食による生活安定は、student mental healthの向上、virtual schooling patternsにおける教育格差の是正、およびschool phone restrictionsなどの学習規律政策と相互に関連しています。

1. Participation Scales and Program Scope
連邦学校給食制度は、米国において2番目に規模の大きい食料セーフティネットです。緊急支援措置を経て、州独自の財源拠出により対象規模が急速に拡大しました。
| Nutrition Program Segment | Daily Participating Students | Participating Schools | Federal Annual Outlay |
|---|---|---|---|
| National School Lunch Program (NSLP) | 30.1 Million | 95,400 | $19.2B |
| School Breakfast Program (SBP) | 15.3 Million | 88,200 | $5.6B |
| Special Milk Program | 0.4 Million | 4,100 | $0.03B |
| Child and Adult Care Food Program (At-Risk) | 1.8 Million | 22,500 | $1.1B |
| Summer EBT (SUN Meals & Grocery Benefits) | 21.0 Million | N/A (Household Benefit) | $2.5B |

2. State-Level Universal Meal Policies
連邦特例措置の終了後、複数の州議会が独自財源を充当して全校生徒の無償化を継続しました。9つの州がこの方針を恒久法として確立しています。
| State Jurisdiction | Enactment Year | State Supplemental Budget | Covered Student Enrollment |
|---|---|---|---|
| California (AB 130) | 2021 (Permanent) | $1.40B Annually | 5.85 Million |
| Maine (LD 1679) | 2021 (Permanent) | $34.0M Annually | 172,000 |
| Minnesota (HF 5) | 2023 (Permanent) | $205.0M Annually | 870,000 |
| New Mexico (SB 4) | 2023 (Permanent) | $30.0M Annually | 315,000 |
| Massachusetts (FY24 Budget) | 2023 (Permanent) | $172.0M Annually | 920,000 |
| Vermont (Act 66) | 2023 (Permanent) | $29.0M Annually | 82,000 |
| Colorado (Prop FF) | 2022 (Permanent) | $115.0M Annually | 885,000 |
| Illinois (Public Act 103-0532) | 2023 (Permanent) | $150.0M Annually | 1.88 Million |

3. Financial Mechanics, Reimbursement, and District Debt
連邦補助金は基本運営費の多くをカバーしますが、インフレやナトリウム基準の厳格化が現場予算を圧迫しています。無償化されていない学区では給食未払い問題が深刻化しています。
| Meal Reimbursement Tier (Contiguous US) | Federal Reimbursement per Lunch | Federal Reimbursement per Breakfast | National Meal Volume Share |
|---|---|---|---|
| Free Meal Rate (Household <= 130% FPL) | $4.33 | $2.37 | 74.2% |
| Reduced-Price Rate (Household <= 185% FPL) | $3.93 | $2.07 | 3.8% |
| Paid Meal Rate (General Household) | $0.43 | $0.40 | 22.0% |
| Performance-Based Certified Additional Reimbursement | +$0.09 | N/A | 98.1% of eligible meals |
| Severe Need Breakfast Differential | N/A | +$0.47 | 76.4% of breakfast programs |

4. Academic, Behavioral, and Health Outcomes
長期的追跡調査により、安定した学校給食の保障は出欠率の向上、問題行動の抑止、および低所得世帯の家計負担軽減に直結することが立証されています。
