Industry 488190 meets CA-51 at $959,830,798.56 in recorded USAspending.gov obligations (22 awards). Twenty-two rows are a small award file relative to this harvest. The cell is 10.8% of California 51st District's $8,872,636,364.50 district total. Other Support Activities For Air Transportation × California 51st District (CA-51) is not California's full federal table and not a cash register. Implied mean $43,628,672.66 is a ratio of two packet facts. Correlation is not causation.

Key figures

  • Air Transportation Support in California 51st District (CA-51): $959,830,798.56 across 22 USAspending awards.
  • Implied mean about $43,628,672.66 per record; district share 10.8% of $8,872,636,364.50.
  • NAICS 488190 × CA-51 is an obligation join, not an outlay and not a named-recipient list.
  • Cite USAspending.gov; quote California 51st District and NAICS 488190 if live tables moved.
  • California federal spending and All spending ties are a parent and an index, not amounts to add into $959,830,798.56.

What the 488190 × CA-51 cell contains

NAICS 488190 and congressional district CA-51 meet here. $959,830,798.56 is the USAspending.gov obligation sum on awards that carry both tags. It is not Other Support Activities For Air Transportation's nationwide total, not every federal dollar coded to California 51st District (CA-51), and not an outlay register. The packet does not split inspection, maintenance, or other air-support lines inside 488190, and it does not split contract versus assistance. 22 is an action count: modifications and repeat awards add rows. Unique recipients are unpublished. This cell is not a hangar roster, a flight-hour log, or a named-MRO list.

Dividing $959,830,798.56 by 22 yields about $43,628,672.66 per award on average. That ratio is two packet facts. It is not a typical MRO contract, hangar line, or air-support award. Twenty-two awards is a small award file. Do not treat CA-51's 488190 cell as a synonym for every Air Transportation Support account nationwide. Open California 51st District (/districts/CA-51/) for the district table without this industry filter, NAICS 488190 (/industries/488190/) for NAICS 488190 without the CA-51 filter, California federal spending (/states/ca/) for every industry in the California extract, and All spending ties (/ties/) for the rest of the join list. Quote those hubs as parents, not as addends to $959,830,798.56.

Industry 488190 without inventing a product pie

USAspending labels industry 488190 as Other Support Activities For Air Transportation. That code produced $959,830,798.56 when crossed with California 51st District (CA-51) place of performance. The industry-wide 488190 hub does not require CA-51 geography. The district hub does not require Air Transportation Support. Only this tie applies both filters, which is why it cites 22 awards. The packet does not split inspection, maintenance, or other air-support lines inside 488190, and it does not split contract versus assistance.

Correlation is not causation: California 51st District (CA-51) did not cause $959,830,798.56 by existing as a large or small place. Population, outcome scores, and named facilities are not packet facts. The join is 488190 × CA-51 only. This cell is not a hangar roster, a flight-hour log, or a named-MRO list. Do not invent contractors or award recipients to fill the gap. Campaign donations on FEC tables do not fund this USAspending cell; the datasets are separate.

Questions

How much Air Transportation Support spending is coded to California 51st District (CA-51)?
USAspending.gov lists $959,830,798.56 in Air Transportation Support (NAICS 488190) obligations across 22 awards coded to California 51st District (CA-51). That pair is an obligation join, not an outlay and not California's complete federal ledger. The cell is 10.8% of the district's published total ($8,872,636,364.50). Unique recipients are unpublished.
Does this include scheduled airline service in CA-51?
NAICS 488190 is other support activities for air transportation, not scheduled passenger service. The packet does not split remaining support lines or contract versus assistance. $959,830,798.56 is the combined obligation sum inside CA-51 coding. This page will not invent an MRO pie or name vendors. 22 remains an action count, not a flight count.
Is $959,830,798.56 cash already paid in California 51st District (CA-51)?
No. Obligations are commitments recorded on USAspending.gov awards. Outlays — money that actually left the Treasury — are a different concept and are not this packet's headline. Treating $959,830,798.56 as checks already cleared in California 51st District (CA-51) confuses those terms. Later ingests can revise 22 awards. Prefer the live district and industry hubs if the tables moved.
Is California 51st District (CA-51) ranked against other California districts here?
No. This page does not rank California 51st District (CA-51) as a winner or loser. $959,830,798.56 and 22 describe one join. Neighboring districts have their own cells. Cite Other Support Activities For Air Transportation and California 51st District (CA-51) together without a league table. Confusing this join with California statewide 488190 totals or CA-51's 811219 repair cell would be a different overlay.

USAspending.gov congressional district place-of-performance joined to NAICS industry. Obligations are not outlays.
