The United States Government Shutdowns and Emergency Declarations. Kofi Aninakwa

      In addition, the longer the shutdown lasts, the worse its impact. Households might deplete savings or hit their credit card limits as the impasse stretches day after day, giving them additional time to adjust their spending in ways that they could not do with only a few days’ notice. For instance, in 2013, bills for health insurance or tuition payments were largely unaffected. Had that shutdown persisted, households may have started to cut back here as well.

      So if Congress refuses to offer furloughed workers back pay and the shutdown lasts weeks rather than days, the economic impact could be severe. However, if a shutdown is resolved in a relatively short amount of time, with workers being paid back their regular income, the damage would likely be fairly contained.

      The third federal government shutdown of Donald Trump's presidency began when a temporary measure to keep the funds flowing at current levels through Feb. 8 collapsed President Trump said he won’t sign a Senate-approved short-term funding bill because it doesn’t contain money for a wall along the nation’s southern border. The bill’s failure boosted the chances of a government shutdown.

      The Office of Management and Budget posted instructions for those federal agencies that could be impacted by what they call a “possible lapse in appropriations from December 22, 2018.” Six of the federal departments, including Defense, already have had their budgets approved and were not impacted.

      But nine other departments and dozens of agencies have been operating under a short-term spending plan that expired at 11:59 p.m. Friday. Funding for those departments will lapse unless Congress approves their budgets or provides another short-term extension. The partial shutdown means that all but essential operations in those departments will be closed and some 800,000 federal employees will be furloughed or forced to work without pay until the standoff is resolved.

      The Departments impacted were Agriculture, Commerce, Justice, Homeland Security, Interior, State, Transportation, Treasury and Housing and Urban Development, as well as several smaller agencies.

      State and local farm service centers operated by the Agriculture Department would close, which means that no staff would be available to answer questions or assist farmers in signing up for new programs under the Farm Bill recently approved by

      Congress, according to a memo prepared by Democrats on the Senate Appropriations Committee.

      National parks could possibly close or offer just limited services. During a shutdown last January, gates at national parks remained open for people to enter but few staff was on hand to protect visitors and park resources. Buildings, such as visitor centers, were shuttered, and sometimes that included restrooms, according to the National Parks Conservation Association.

      More than 30 million small businesses would no longer have access to federally assisted loans and technical assistance since Small Business Administration guarantees to back loans would freeze. Americans looking to buy a new home or refinance a mortgage insured by the Federal House Administration would be put on standby. Civil litigation, payments to victims and training for state and local law enforcement would stop during a shutdown.

       How will federal workers be affected?

      More than 420,000 federal workers who provide essential services will be forced to work without pay, according to Democrats’ memo. That includes 41,000 federal law enforcement and corrections officers, such as prisons officials, FBI agents, U.S. marshals and Drug Enforcement Administration workers. Also affected will be most customs and border patrol agents, Coast Guard employees, Transportation Security Administration officials, federal firefighters and weather service forecasters.

      Another 380,000 federal workers will be furloughed, including most of workers at Commerce, NASA, the National Park Service, the Forest Service and Housing and Urban Development. Roughly a third of federal transportation workers will be furloughed, as will some 52,000 Internal Revenue Service workers.

       What won’t be affected?

       The mail. The Postal Service is an independent agency and won't be impacted in any government shutdown.

       Travel. Air-traffic controllers still will be on the job and customs and border agents will continue working at border crossings. Amtrak, a government-owned corporation, also will operate as usual.

       Social Security checks. Social Security benefits still go out, as will Medicare services and benefits from programs such as the Supplemental Nutritional Assistance Program and Women, Infants and Children for at least as long as some carryover money in the states or the federal accounts are available.

       Congress has two jobs to do: pass a budget and pay its bills. Congress failed to fulfill its responsibility to pass a budget and as a result, much of the Federal government was shut down. An overview of some of the government services and operations that were impacted until Congress passes a budget to fund them again.

       Vital services that ensure seniors and young children have access to healthy food and meals may not have sufficient Federal funds to serve all beneficiaries in an extended lapse.

       Call centers, hotlines and regional offices that help veterans understand their benefits will close to the public.

       Veterans’ compensation, pension, education and other benefits could be cut off in the case of an extended shutdown.

       Every one of America’s national parks and monuments, from Yosemite to the Smithsonian to the Statue of Liberty, was immediately closed.

       New and unprocessed applications for small business loans and loan guarantees were immediately halted.

       Research into life-threatening diseases and other areas were stop and new patients won’t be accepted into clinical trials at the National Institutes of Health.

       Work to protect consumers, ranging from child product safety to financial security to the safety of hazardous waste facilities, will cease. The EPA halted non-essential inspections of chemical facilities and drinking water systems.

       Permits and reviews for planned energy and transportations projects stopped, preventing companies from working on these projects.

       Loans to rural communities were halted.

       Hundreds of thousands of Federal employees including many charged with protecting the country from terrorist threats, defending our borders, inspecting our food, and keeping our skies safe will work without pay until the shutdown ends.

       Hundreds of thousands of additional Federal workers will be immediately and indefinitely be furloughed without pay.

      The following services that will continue during the government shut down:

       Social security beneficiaries will continue receiving checks.

       Active military will continue serving.

       Air traffic controllers, prison guards and border patrol agents will remain on the job.

       NASA Mission Control will continue supporting astronauts
