Your head badge says Chicago, so you got USA.
My Schwinn was made in Japan.
Not always. For instance, Schwinn used the Schwinn Chicago badge long after the Chicago plant was closed. Its kind of like Boeing, their headquarters is Chicago but they don't make a single plane there. I have several Japan made Schwinns that do not have a Japan head badge. I've also had a 1984 Schwinn High Sierra with a 1970s Schwinn Chicago Paramount head badge (I am not alone in this, others have had the same). HS was made in Taiwan by Giant. Serial number tells the tale.
A Panasonic built Schwinn will have a distinct, unique serial number of the head tube. A Giant built Schwinn will typically have a date code on the non-drive side drop out. After 1982, the better USA built Schwinns were made in Greenville, MS. We can debate quality, but IMO, many of the Japanese built Schwinns of that era were higher quality, like my 1987 Schwinn Prologue. Some of the lower end USA built Schwinns in the early 1980s were made by Murray, not exactly a great source.
Having grown up in the era where Japanese made bikes were just starting to enter the market (1973+/-), I did not give them near the respect that I should have at the time. Now looking back I realize my mistake.
