The Roman Catholic Archdiocese of Washington, in the first public disclosure of such figures in its history, has estimated the value of its land and buildings here at $236,183,047.

The figures represent real estate owned both by the archdiocese and its 127 parishes in the District of Columbia and five Maryland counties. All church-owned property is tax-emempt exvept for a few properties not used for church pruposes on which the archdiocese paid $53,046 in property taxes last year.

The value of the properties was based largely on "an insurance agent's appraised value (of them) as of June 30, 1976," according to the accounting firm of Haskins and Sells, which audited the reports.

Not included in the real estate total was the voluation of furnishings and equipment set at $11,337,276.

While the archdiocese previously has released an accounting of its own financial picture, theis disclosure is the first public accounting of the consolidated parishes.

According to the reports released last week, the archdiocese itself managed to trim almost almost $500,000 from its operating deficit in the fiscal year ending last June 30. The deficit was $195,624.

Progress toward a balanced budget came at the cost of cuts in aid to Catholic schools and some services to the poor.

School subsidies, designed to ease the burden of parochial school tuition payments by poor Catholic parents, continued to be the largest single continued to be the largest single item in the 1976 archdiocesan operating budget of $3.5 million.

The 1976 subsidy total of $667,414 for secondary and high schools was down $127,106 from the year before.

Subsidies go largely to inner-city schools and those in low-income secontions of Southern Maryland.

The budget for the archdiocesan Office of Education was slashed more than 40 per cent - from $151,247 in 1975 to $83,506. Archdiocesan grants to poor parishes were cut from $206,483 in 1975 to $116,519.

The Office of Social Development, which deals with inner-city concerns, had more than $28,000 cut from its 1975 budget of $116,517.

Catholic Youth Organization lost $26,864 from its 1975 total of $100,114. The Confraternity of Christian Doctrine office, which teaches the faith to youngsters who do not attend Catholi schools, lost almost $20,000 from its $95,049 total of 1975.

The Archdiocese of Washington lists a total membership of 396,421 persons.

Neither the archdiocesan nor consolidated parish financial reports include hospitals, colleges r institutions of religious orders located in the area.

The consolidated parishes do not include the National Shrine of the Immaculate Conception, or the Catholic University campus. The shrine, which belongs to the American Catholic hierarchy, has its own budget, land is supervised by the National Conference of Catholic Bishops.

Public disclosure of financial affairs of the Church was encouraged by teh Second Vatican Council f a decade ago as part of a move toward greater involvement of lay members in church affairs.

Msgr. William F. Farrell, secretary of finances for the archdiocese, said the report of the consolidated parishes was made possible bny a system of unified accounting procedures for all parishes recently instituted by the archdiocese.

The Diocese of Arlington has published a much more abbreviated finance report which showed a $175,061 deficit for the 1975-76 fiscal year. The diocese, with 51 parishes, spent a total of $1,812,263 during the fiscal year.

Work with Vietnamese refugees was the largest single expenditure - $657,537 - in that diocesan report.
