Estimated Congressional Appropriations and Spending in Current Billions of U.S. Dollars, Excluding Future Interest Payments and Future Costs for Veterans Care

Since invading Afghanistan in 2001, the United States has spent $2.26 trillion on the war, which includes operations in both Afghanistan and Pakistan. Note that this total does not include funds that the United States government is obligated to spend on lifetime care for American veterans of this war, nor does it include future interest payments on money borrowed to fund the war.

2 This chart tallies estimated direct deaths caused by war violence. It does not include indirect deaths, namely those caused by loss of access to food, water, and/or infrastructure, and war-related disease, etc. The numbers included here are approximations based on the reporting of several original data sources. Most, though not all, original data sources are updated through 2020 or early 2021; dates are noted in the foot notes. Some original data sources are incomplete, inconsistent and/or data is inaccessible. Thus, for the most part, these data are estimated. The totals are rounded to indicate that there is a degree uncertainty in these counts.

4 In Operations Enduring Freedom and Freedom’s Sentinel.

7 Estimate based on United States Department of Labor (DOL) (2019). Defense Base Act Case Summary by Nation. Retrieved from: https://www.dol.gov/owcp/dlhwc/dbaallnation.htm (data through March 31, 2020).

The figure given here is an estimate of total contractor deaths based on DOL numbers, namely the additional number of unreported contractor deaths by comparing the percentage of foreign contractors working for the US military in the warzone with the much lower percentage of foreign contractors among the reported contractor dead. The multiplier reflecting this disparity is 2.15 times the DOL number. DOL data for contractor deaths: Afghanistan, 1,789; Pakistan, 42.

8 Includes National Military Forces and National and Local Police Forces.

9 There is uncertainty about the number of Afghan National Police and military deaths. This estimate is based on several source s. In September 2013, US General Joseph Dunford said that more than 100 Afghan Security Forces were being killed a week. Harrison, Emma Graham (2013, Sept. 2), “Afghan Forces Suffering Too Many Casualties Says Top NATO Commander,” The Guardian, retrieved from https://www.theguardian.com/world/2013/sep/02/afghan-forces.

In March 2014, The New York Times reported 13,729 Afghan National Security and Police deaths from 2001 to 2014. Nordland, Rod (2014, March 3), “War Deaths Top 13,000 in Afghan Security Forces,” The New York Times, retrieved from https://www.nytimes.com/2014/03/04/world/asia/afghan-cabinet-releases-data-on-deaths-of-security-personnel.html?partner=rss&emc=rss&smid=tw-nytimes&_r=0.

In January 2017, the Special Inspector General for Afghanistan Reconstruction (SIGAR) reported 6,785 Afghan National Defense and Security Forces (ANDSF) killed from January 1, 2016 to November 12, 2016, a rate of about 147 per week.: https://www.sigar.mil/pdf/quarterlyreports/2017-01-30qr.pdf.

In September 2018, Afghan President Ashraf Ghani said 28,529 Afghan security forceshad been killed since 2015. Fahim Abed and Rod Nordland, “Afghan War Casualty Report: Nov. 9-15” The New York Times, https://www.nytimes.com/2018/11/15/magazine/afghan-war-casualty-report.html?module=inline.

In January 2019, President Ashraf Ghani said that there have been 45,000 security personnel killed since he took office in September 2014. See BBC (2019, January 25), “Afghanistan’s Ghani says 45,000 Security Personnel Killed Since 2014,” BBC News, https://www.bbc.com/news/world-asia-47005558.

Assuming that 100 Afghan ANSDF were killed each week from April through August 2014, this adds an additional 2,000 deaths. The New York Times reported 3,395 Afghan security force deaths for the period January 1, 2019 to October 31, 2019. Fahim Abed, “Afghan War Casualty Report,” The New York Times for each week from January 1 to October 31, 2019. US Forces in Afghanistan began to classify these numbers in 2017 after previously releasing them. See Thomas Gibbons-Neff (2017, October 30), “Afghan War Data, Once Public, is Censored in U.S. Military Report,” The New York Times, retrieved from https://www.nytimes.com/2017/10/30/world/asia/afghanistan-war-redacted-report.html, and

In December 2017, the DOD reported that the “number of ANDSF casualties suffered while conducting local patrols and checkpoint operations was similar to that of 2016,” while “the number of casualties in planned operations has decreased over the same period.” See Department of Defense, “Enhancing Security and Stability in Afghanistan”: https://www.defense.gov/Portals/1/Documents/pubs/1225-Report-Dec- 2017.pdf.

These civilian death numbers include the recorded direct violent deaths. Additional direct violent deaths may not have been recorded and significant numbers of indirect deaths due to displacement or destruction of infrastructure have not been included.

This data is mostly consistent with South Asia Terrorism Portal, “Fatalities in Terrorist Violence in Pakistan 2003-2018,” retrieved from www.satp.org/satporgtp/countries/pakistan/database/casualties.htm.

The counts of the dead (and wounded) are complicated not only by the difficulty of access to war zones for investigators, but also because some actors have incentives to either exaggerate or to minimize the number of civilians killed, or to identify civilians as militants.

14 Neither the US or NATO have released figures on the exact number of anti-government insurgents killed. From July 1 through November 5, 2019, Afghan National Defense Forces reported killing 10,259 militants/insurgents/terrorists and reported killing 10,091 from 6 November to 13 April 2021. They did not report any data for the period of May through August 2020. https://mod.gov.af/en/press-release.
