Discover the historical likelihood of you or a male relative being drafted into the United States Armed Forces during the peak period of World War II (1943), based on historical criteria like age, fitness, and marital status.

Detailed Eligibility Analysis (Based on 1943 Criteria)
WWII Draft Eligibility Formula (Likelihood Score)
The calculation uses a weighted historical score based on typical induction priorities of 1943, where a higher score indicates a higher likelihood of receiving a 1-A classification and induction.
Likelihood Score = Σ (Input Weightings)
Input Weightings:
- Age (18-37): +40 points
- Physically Fit (1-A): +30 points
- Single/No Dependents: +20 points
- Non-Essential Job: +10 points

Variables Explained
Each variable is critical to determining the likelihood of being called up:
- Birth Year: Used to calculate the applicant’s age during the peak induction year of 1943. The primary induction age range was 18 to 37.
- Physical and Mental Fitness: Equivalent to the 1-A (Fit for Service) and 4-F (Unfit for Service) Selective Service classifications.
- Marital Status/Dependents: Men with dependents (especially fathers) received the highest deferment priority (3-A), making their induction less likely until later in the war.
- Essential Occupation: Workers in key industries (e.g., aircraft manufacturing, farming, mining) were often granted occupational deferments (2-A/2-B) to support the war effort at home.

What is WWII Draft Eligibility?
The WWII Draft, managed by the U.S. Selective Service System, mandated the registration of nearly all men between 18 and 64, but only those between 18 and 37 were typically inducted. Eligibility was a complex matrix of age, physical standards, dependency status, and essential occupation. The needs of the military evolved rapidly, meaning deferment categories (like 3-A for fathers) that offered protection early on were often dissolved as manpower requirements increased later in the war.
The core eligibility for induction was the 1-A classification—a fit, available, single male with no essential occupation. Every other classification (2-A, 3-A, 4-F) represented a potential reason for deferment or exemption. The calculator models these historical probabilities to give a generalized likelihood.
How to Calculate Draft Status (Example)
Using our score-based method, here is a step-by-step example for a single, fit, 20-year-old worker in a non-essential job:
- Determine Age Eligibility: Birth Year 1923 (Age 20 in 1943). Since 20 is within the 18-37 induction range, add 40 points.
- Determine Physical Status: The individual is ‘Fit for General Service.’ Add 30 points.
- Determine Marital Status: The individual is ‘Single, No Dependents.’ This makes them a high priority. Add 20 points.
- Determine Occupation Status: The individual is in a ‘Non-essential Civilian Job.’ Add 10 points.
- Calculate Final Score: $40 + 30 + 20 + 10 = 100$.
- Determine Likelihood: A score of 100 places the individual in the Highly Likely category for immediate induction.
Frequently Asked Questions (FAQ)
What was the most important factor for deferment?
Initially, being a father (3-A) provided the strongest protection. However, by late 1943, even 3-A status was being phased out due to massive military needs, making physical fitness (4-F) and an indispensable essential job the final major barriers to induction.
Did the draft apply to all races equally?
All male citizens were required to register. While registration was universal, induction and assignment were subject to the prevailing segregation policies of the U.S. military during WWII, leading to racial discrimination in unit assignments and opportunities.
What age groups were required to register?
Between 1940 and 1947, six registration rounds were conducted. By the end, virtually all men between the ages of 18 and 64 were registered, although the age range for actual induction into military service remained primarily 18 to 37.
What does a 4-F classification mean?
A 4-F classification meant the registrant was judged “Unfit for military service” due to physical, mental, or moral disqualifications. This was a non-negotiable exemption from induction.
