[3] The district consists of the old provincial capital, Leyte, and adjacent municipalities of Calubian, San Isidro, Tabango and Villaba.

It is currently represented in the 18th Congress by Anna Victoria V. Tuazon of the National Unity Party (NUP).

[4] Until 1931, it consisted of the north-central municipalities of Abuyog, Barugo, Burauen, Capoocan, Carigara, Dagami, Hinunangan, Hinundayan, Jaro, La Paz, and Pastrana.

Following the creation of the fifth district, it was redefined to consist of the southern municipalities of undivided Leyte that now form part of Southern Leyte,[5] until they were transferred to the new province's at-large district in 1961, three years after its establishment.

The district was subsequently redefined to consist of the sub-province of Biliran and the northern municipalities of Calubian, Isabel, Leyte, Matag-ob, Merida, Palompon, San Isidro, Tabango, and Villaba, all previously from the first district, from 1961 until its second dissolution in 1972.
